 ###Creating a chart
 
-To create a chart, we need to instantiate the `Chart` class. To do this, we need to pass in the node, jQuery instance, or 2d context of the canvas of where we want to draw the chart. Here's an example.
+To create a chart, we need to instantiate the `Chart` class. To do this, we need to pass in the 2d context of where we want to draw the chart. Here's an example.
 
 ```html
 <canvas id="myChart" width="400" height="400"></canvas>
 ```
 
 ```javascript
-// Any of the following formats may be used
-var ctx = document.getElementById("myChart");
+// Get the context of the canvas element we want to select
 var ctx = document.getElementById("myChart").getContext("2d");
-var ctx = $("myChart");
+var myNewChart = new Chart(ctx).PolarArea(data);
 ```
 
-Once you have the element or context, you're ready to instantiate a pre-defined chart-type or create your own!
+We can also get the context of our canvas with jQuery. To do this, we need to get the DOM node out of the jQuery collection, and call the `getContext("2d")` method on that.
 
-The following example instantiates a the pre-defined Polar Area chart type with a config object of data and options.
 ```javascript
-var myNewChart = Chart.PolarArea(ctx, {
-    data: data,
-    options: options
-});
+// Get context with jQuery - using jQuery's .get() method.
+var ctx = $("#myChart").get(0).getContext("2d");
+// This will get the first returned node in the jQuery collection.
+var myNewChart = new Chart(ctx);
 ```
 
-To create a scatter chart, which is a special configuration of a line chart, we use the following.
+After we've instantiated the Chart class on the canvas we want to draw on, Chart.js will handle the scaling for retina displays.
+
+With the Chart class set up, we can go on to create one of the charts Chart.js has available. In the example below, we would be drawing a Polar area chart.
+
 ```javascript
-var myScatterChart = Chart.Scatter(ctx, {
-    data: data,
-    options: options
-});
+new Chart(ctx).PolarArea(data, options);
 ```
 
-Alternatively, we can use the more advanced API to create simple or advanced chart types. In the example below, we are creating a line chart.
-```javascript
-var myChart = new Chart(ctx, {
-    type: 'line', // built in types are 'line', 'bar', 'radar', 'polarArea', 'doughnut', 'scatter'
-    data: data,
-    options: options
-});
-```
+We call a method of the name of the chart we want to create. We pass in the data for that chart type, and the options for that chart as parameters. Chart.js will merge the global defaults with chart type specific defaults, then merge any options passed in as a second argument after data.
 
 ###Global chart configuration
 
 This concept was introduced in Chart.js 1.0 to keep configuration DRY, and allow for changing options globally across chart types, avoiding the need to specify options for each instance, or the default for a particular chart type.
 
-Chart.js merges configurations and options in a few places with the global defaults using chart type defaults and scales defaults. This way you can be as specific as you want in your individual chart configs, or change the defaults for Chart.js as a whole.
+Templates are based on micro templating by John Resig:
+
+http://ejohn.org/blog/javascript-micro-templating/
 
 ```javascript
 Chart.defaults.global = {

-    responsiveAnimationDuration: 0,

+title: Line Chart
+anchor: line-chart
+---
+###Introduction
+A line chart is a way of plotting data points on a line.
+
+Often, it is used to show trend data, and the comparison of two data sets.
+
+<div class="canvas-holder">
+	<canvas width="250" height="125"></canvas>
+</div>
+
+###Example usage
+```javascript
+var myLineChart = new Chart(ctx).Line(data, options);
+```
+###Data structure
+
+```javascript
+var data = {
+	labels: ["January", "February", "March", "April", "May", "June", "July"],
+	datasets: [
+		{
+			label: "My First dataset",
+			fillColor: "rgba(220,220,220,0.2)",
+			strokeColor: "rgba(220,220,220,1)",
+			pointColor: "rgba(220,220,220,1)",
+			pointStrokeColor: "#fff",
+			pointHighlightFill: "#fff",
+			pointHighlightStroke: "rgba(220,220,220,1)",
+			data: [65, 59, 80, 81, 56, 55, 40]
+		},
+		{
+			label: "My Second dataset",
+			fillColor: "rgba(151,187,205,0.2)",
+			strokeColor: "rgba(151,187,205,1)",
+			pointColor: "rgba(151,187,205,1)",
+			pointStrokeColor: "#fff",
+			pointHighlightFill: "#fff",
+			pointHighlightStroke: "rgba(151,187,205,1)",
+			data: [28, 48, 40, 19, 86, 27, 90]
+		}
+	]
+};
+```
+
+The line chart requires an array of labels. This labels are shown on the X axis. There must be one label for each data point. More labels than datapoints are allowed, in which case the line ends at the last data point.
+The data for line charts is broken up into an array of datasets. Each dataset has a colour for the fill, a colour for the line and colours for the points and strokes of the points. These colours are strings just like CSS. You can use RGBA, RGB, HEX or HSL notation.
+
+The label key on each dataset is optional, and can be used when generating a scale for the chart.
+
+### Chart options
+
+These are the customisation options specific to Line charts. These options are merged with the [global chart configuration options](#getting-started-global-chart-configuration), and form the options of the chart.
+
+```javascript
+{
+
+	///Boolean - Whether grid lines are shown across the chart
+	scaleShowGridLines : true,
+
+	//String - Colour of the grid lines
+	scaleGridLineColor : "rgba(0,0,0,.05)",
+
+	//Number - Width of the grid lines
+	scaleGridLineWidth : 1,
+
+	//Boolean - Whether to show horizontal lines (except X axis)
+	scaleShowHorizontalLines: true,
+
+	//Boolean - Whether to show vertical lines (except Y axis)
+	scaleShowVerticalLines: true,
+
+	//Boolean - Whether the line is curved between points
+	bezierCurve : true,
+
+	//Number - Tension of the bezier curve between points
+	bezierCurveTension : 0.4,
+
+	//Boolean - Whether to show a dot for each point
+	pointDot : true,
+
+	//Number - Radius of each point dot in pixels
+	pointDotRadius : 4,
+
+	//Number - Pixel width of point dot stroke
+	pointDotStrokeWidth : 1,
+
+	//Number - amount extra to add to the radius to cater for hit detection outside the drawn point
+	pointHitDetectionRadius : 20,
+
+	//Boolean - Whether to show a stroke for datasets
+	datasetStroke : true,
+
+	//Number - Pixel width of dataset stroke
+	datasetStrokeWidth : 2,
+
+	//Boolean - Whether to fill the dataset with a colour
+	datasetFill : true,
+	{% raw %}
+	//String - A legend template
+	legendTemplate : "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<datasets.length; i++){%><li><span style=\"background-color:<%=datasets[i].strokeColor%>\"><%if(datasets[i].label){%><%=datasets[i].label%><%}%></span></li><%}%></ul>"
+	{% endraw %}
+
+	//Boolean - Whether to horizontally center the label and point dot inside the grid
+	offsetGridLines : false
+};
+```
+
+You can override these for your `Chart` instance by passing a second argument into the `Line` method as an object with the keys you want to override.
+
+For example, we could have a line chart without bezier curves between points by doing the following:
+
+```javascript
+new Chart(ctx).Line(data, {
+	bezierCurve: false
+});
+// This will create a chart with all of the default options, merged from the global config,
+// and the Line chart defaults, but this particular instance will have `bezierCurve` set to false.
+```
+
+We can also change these defaults values for each Line type that is created, this object is available at `Chart.defaults.Line`.
+
+
+### Prototype methods
+
+#### .getPointsAtEvent( event )
+
+Calling `getPointsAtEvent(event)` on your Chart instance passing an argument of an event, or jQuery event, will return the point elements that are at that the same position of that event.
+
+```javascript
+canvas.onclick = function(evt){
+	var activePoints = myLineChart.getPointsAtEvent(evt);
+	// => activePoints is an array of points on the canvas that are at the same position as the click event.
+};
+```
+
+This functionality may be useful for implementing DOM based tooltips, or triggering custom behaviour in your application.
+
+#### .update( )
+
+Calling `update()` on your Chart instance will re-render the chart with any updated values, allowing you to edit the value of multiple existing points, then render those in one animated render loop.
+
+```javascript
+myLineChart.datasets[0].points[2].value = 50;
+// Would update the first dataset's value of 'March' to be 50
+myLineChart.update();
+// Calling update now animates the position of March from 90 to 50.
+```
+
+#### .addData( valuesArray, label )
+
+Calling `addData(valuesArray, label)` on your Chart instance passing an array of values for each dataset, along with a label for those points.
+
+```javascript
+// The values array passed into addData should be one for each dataset in the chart
+myLineChart.addData([40, 60], "August");
+// This new data will now animate at the end of the chart.
+```
+
+#### .removeData( )
+
+Calling `removeData()` on your Chart instance will remove the first value for all datasets on the chart.
+
+```javascript
+myLineChart.removeData();
+// The chart will remove the first point and animate other points into place
+```

-###Scales
-
-Scales in v2.0 of Chart.js are significantly more powerful, but also different than those of v1.0.
-- Multiple x & y axes are now supported.
-- A built-in label auto-skip feature now detects would-be overlapping ticks and labels and removes every nth label to keep things displaying normally. 
-- Scale labels
-
-Every scale extends a core scale class with the following options:
-
-```javascript
-Chart.defaults.scale = {
-	display: true,
-
-	// grid line settings
-	gridLines: {
-		show: true,
-		color: "rgba(0, 0, 0, 0.1)",
-		lineWidth: 1,
-		drawOnChartArea: true,
-		drawTicks: true,
-		zeroLineWidth: 1,
-		zeroLineColor: "rgba(0,0,0,0.25)",
-		offsetGridLines: false,
-	},
-
-	// scale label
-	scaleLabel: {
-		fontColor: '#666',
-		fontFamily: 'Helvetica Neue',
-		fontSize: 12,
-		fontStyle: 'normal',
-
-		// actual label
-		labelString: '',
-
-		// display property
-		show: false,
-	},
-
-	// label settings
-	ticks: {
-		beginAtZero: false,
-		fontSize: 12,
-		fontStyle: "normal",
-		fontColor: "#666",
-		fontFamily: "Helvetica Neue",
-		maxRotation: 90,
-		minRotation: 20,
-		mirror: false,
-		padding: 10,
-		reverse: false,
-		show: true,
-		template: "<%=value%>",
-		userCallback: false,
-	},
-};
-```
-
-The `userCallback` method may be used for advanced tick customization. The following callback would display every label in scientific notation
-```javascript
-{
-    scales: {
-        xAxes: [{
-            ticks: {
-                // Return an empty string to draw the tick line but hide the tick label
-                // Return `null` or `undefined` to hide the tick line entirely
-               	userCallback: function(value, index, values) {
-    				return value.toExponential();
-    			}
-            }
-        }]
-    }
-}
-```
-
-#### Category Scale
-The category scale will be familiar to those who have used v1.0. Labels are drawn in from the labels array included in the chart data.
-
-The category scale extends the core scale class with the following tick template:
-
-```javascript
-{
-	position: "bottom",
-}
-```
-
-#### Linear Scale
-The linear scale can be used to display numerical data. It can be placed on either the x or y axis. The scatter chart type automatically configures a line chart to use one of these scales for the x axis.
-
-The linear scale extends the core scale class with the following tick template:
-
-```javascript
-{
-	position: "left",
-}
-```
-
-#### Logarithmic Scale
-The logarithmic scale is used to display logarithmic data of course. It can be placed on either the x or y axis.
-
-The log scale extends the core scale class with the following tick template:
-
-```javascript
-{
-	position: "left",
-	ticks: {
-		template: "<%var remain = value / (Math.pow(10, Math.floor(Chart.helpers.log10(value))));if (remain === 1 || remain === 2 || remain === 5) {%><%=value.toExponential()%><%} else {%><%= null %><%}%>",
-	}
-}
-```
-
-#### Time Scale
-The time scale is used to display times and dates. It can be placed on the x axis. When building its ticks, it will automatically calculate the most comfortable unit base on the size of the scale.
-
-The time scale extends the core scale class with the following tick template:
-
-```javascript
-{
-	position: "bottom",
-	time: {
-		// string/callback - By default, date objects are expected. You may use a pattern string from http://momentjs.com/docs/#/parsing/string-format/ to parse a time string format, or use a callback function that is passed the label, and must return a moment() instance.
-		format: false,
-		// string - By default, unit will automatically be detected.  Override with 'week', 'month', 'year', etc. (see supported time measurements)
-		unit: false, 
-		// string - By default, no rounding is applied.  To round, set to a supported time unit eg. 'week', 'month', 'year', etc.
-		round: false, 
-		// string - By default, is set to the detected (or manually overridden) time unit's `display` property (see supported time measurements).  To override, use a pattern string from http://momentjs.com/docs/#/displaying/format/
-		displayFormat: false
-	},
-}
-```
-
-The following time measurements are supported:
-
-```javascript
-{
-	'millisecond': {
-		display: 'SSS [ms]', // 002 ms
-		maxStep: 1000,
-	},
-	'second': {
-		display: 'h:mm:ss a', // 11:20:01 AM
-		maxStep: 60,
-	},
-	'minute': {

-	},
-	'week': {
-		display: 'll', // Week 46, or maybe "[W]WW - YYYY" ?
-		maxStep: 4.3333,

-
-#### Radial Linear Scale
-The radial linear scale is used specifically for the radar chart type.
-
-The radial linear scale extends the core scale class with the following tick template:
-
-```javascript

-	lineArc: false,
-	position: "chartArea",
-
-	angleLines: {
-		show: true,
-		color: "rgba(0, 0, 0, 0.1)",

-	ticks: {
-		//Boolean - Show a backdrop to the scale label
-		showLabelBackdrop: true,
-
-		//String - The colour of the label backdrop
-		backdropColor: "rgba(255,255,255,0.75)",
-
-		//Number - The backdrop padding above & below the label in pixels
-		backdropPaddingY: 2,
-
-		//Number - The backdrop padding to the side of the label in pixels
-		backdropPaddingX: 2,
-	},
-
-	pointLabels: {
-		//String - Point label font declaration
-		fontFamily: "'Arial'",
-
-		//String - Point label font weight
-		fontStyle: "normal",
-
-		//Number - Point label font size in pixels

+### Introduction
+A bar chart is a way of showing data as bars.
+
+It is sometimes used to show trend data, and the comparison of multiple data sets side by side.
+
+<div class="canvas-holder">
+	<canvas width="250" height="125"></canvas>
+</div>
+
+### Example usage
+```javascript
+var myBarChart = new Chart(ctx).Bar(data, options);
+```
+
+### Data structure
+
+```javascript
+var data = {
+	labels: ["January", "February", "March", "April", "May", "June", "July"],
+	datasets: [
+		{
+			label: "My First dataset",
+			fillColor: "rgba(220,220,220,0.5)",
+			strokeColor: "rgba(220,220,220,0.8)",
+			highlightFill: "rgba(220,220,220,0.75)",
+			highlightStroke: "rgba(220,220,220,1)",
+			data: [65, 59, 80, 81, 56, 55, 40]
+		},
+		{
+			label: "My Second dataset",
+			fillColor: "rgba(151,187,205,0.5)",
+			strokeColor: "rgba(151,187,205,0.8)",
+			highlightFill: "rgba(151,187,205,0.75)",
+			highlightStroke: "rgba(151,187,205,1)",
+			data: [28, 48, 40, 19, 86, 27, 90]
+		}
+	]
+};
+```
+The bar chart has the a very similar data structure to the line chart, and has an array of datasets, each with colours and an array of data. Again, colours are in CSS format.
+We have an array of labels too for display. In the example, we are showing the same data as the previous line chart example.
+
+The label key on each dataset is optional, and can be used when generating a scale for the chart.
+
+### Chart Options
+
+These are the customisation options specific to Bar charts. These options are merged with the [global chart configuration options](#getting-started-global-chart-configuration), and form the options of the chart.
+
+```javascript

+You can override these for your `Chart` instance by passing a second argument into the `Bar` method as an object with the keys you want to override.
+
+For example, we could have a bar chart without a stroke on each bar by doing the following:
+
+```javascript
+new Chart(ctx).Bar(data, {
+	barShowStroke: false
+});
+// This will create a chart with all of the default options, merged from the global config,
+//  and the Bar chart defaults but this particular instance will have `barShowStroke` set to false.
+```
+
+We can also change these defaults values for each Bar type that is created, this object is available at `Chart.defaults.Bar`.
+

+#### .getBarsAtEvent( event )
+
+Calling `getBarsAtEvent(event)` on your Chart instance passing an argument of an event, or jQuery event, will return the bar elements that are at that the same position of that event.
+
+```javascript
+canvas.onclick = function(evt){
+	var activeBars = myBarChart.getBarsAtEvent(evt);
+	// => activeBars is an array of bars on the canvas that are at the same position as the click event.
+};
+```
+
+This functionality may be useful for implementing DOM based tooltips, or triggering custom behaviour in your application.
+
+#### .update( )
+
+Calling `update()` on your Chart instance will re-render the chart with any updated values, allowing you to edit the value of multiple existing points, then render those in one animated render loop.
+
+```javascript
+myBarChart.datasets[0].bars[2].value = 50;
+// Would update the first dataset's value of 'March' to be 50
+myBarChart.update();
+// Calling update now animates the position of March from 90 to 50.
+```
+
+#### .addData( valuesArray, label )
+
+Calling `addData(valuesArray, label)` on your Chart instance passing an array of values for each dataset, along with a label for those bars.

-###Introduction
-A line chart is a way of plotting data points on a line.
-
-Often, it is used to show trend data, and the comparison of two data sets.
-
-<div class="canvas-holder">
-	<canvas width="250" height="125"></canvas>
-</div>
-
-###Example usage
-```javascript
-var myLineChart = new Chart(ctx, {
-	type: 'line',
-	data: data, 
-	options: options
-});
-```
-
-Alternatively a line chart can be created using syntax similar to the v1.0 syntax
-```javascript
-var myLineChart = Chart.Line(ctx, {
-	data: data, 
-	options: options
-});
-```
-###Data structure
-
-```javascript
-var data = {
-	labels: ["January", "February", "March", "April", "May", "June", "July"],
-	datasets: [
-		{
-			label: "My First dataset",
-
-			// Boolean - if true fill the area under the line
-			fill: false,
-
-			// String - the color to fill the area under the line with if fill is true
-			backgroundColor: "rgba(220,220,220,0.2)",
-
-			// The properties below allow an array to be specified to change the value of the item at the given index
-
-			// String or array - Line color
-			borderColor: "rgba(220,220,220,1)",
-
-			// String - cap style of the line. See https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/lineCap

-			// String - If specified, binds the dataset to a certain y-axis. If not specified, the first y-axis is used.
-			yAxisID: "y-axis-1",
-		},
-		{
-			label: "My Second dataset",
-			fill: false,
-			backgroundColor: "rgba(220,220,220,0.2)",

-			pointHoverBorderWidth: 2,
-			data: [28, 48, 40, 19, 86, 27, 90]
-		}
-	]
-};
-```
-
-The line chart requires an array of labels for each of the data points. This is shown on the X axis.
-The data for line charts is broken up into an array of datasets. Each dataset has a colour for the fill, a colour for the line and colours for the points and strokes of the points. These colours are strings just like CSS. You can use RGBA, RGB, HEX or HSL notation.
-
-The label key on each dataset is optional, and can be used when generating a scale for the chart.
-
-### Chart options
-
-These are the customisation options specific to Line charts. These options are merged with the [global chart configuration options](#getting-started-global-chart-configuration), and form the options of the chart.
-
-```javascript
-{
-	// Boolean - if true, line stack on top of each other along the y axis
-	stacked: false,
-
-	hover: {
-		// String - We use a label hover mode since the x axis displays data by the index in the dataset
-		mode: "label"
-	},
-
-	scales: {
-		// Defines all of the x axes used in the chart. See the [scale documentation](#getting-started-scales) for details on the available options
-		xAxes: [{
-			// String - type of scale. Built in types are 'category' and 'linear'
-			type: 'category', 
-
-			// String - id of the axis so that data can bind to it
-    		id: "x-axis-1", // need an ID so datasets can reference the scale
-		}],
-
-		// Defines all of the y axes used in the chart.
-		// By default, the line chart uses a linear scale along the y axis
-		yAxes: [{
-			type: 'linear',
-
-			// String - ID of the axis for data binding
-    		id: "y-axis-1",
-		}],
-	}
-};
-```
-
-You can override these for your `Chart` instance by passing a member `options` into the `Line` method.
-
-For example, we could have a line chart display without an x axis by doing the following. The config merge is smart enough to handle arrays so that you do not need to specify all axis settings to change one thing.
-
-```javascript
-new Chart(ctx, {
-	type: 'line',
-	data: data, 
-	options: {
-		xAxes: [{
-			show: false
-		}]
-	}
-});
-// This will create a chart with all of the default options, merged from the global config,
-// and the Line chart defaults, but this particular instance will have `bezierCurve` set to false.
-```
-
-We can also change these defaults values for each Line type that is created, this object is available at `Chart.defaults.Line`.
-
-
-### Prototype methods
-
-#### .getElementsAtEvent( event )
-
-Calling `getElementsAtEvent(event)` on your Chart instance passing an argument of an event, or jQuery event, will return the point elements that are at that the same position of that event.
-
-```javascript
-canvas.onclick = function(evt){
-	var activePoints = myLineChart.getElementsAtEvent(evt);
-	// => activePoints is an array of points on the canvas that are at the same position as the click event.
-};
-```
-
-This functionality may be useful for implementing DOM based tooltips, or triggering custom behaviour in your application.
-
-#### .update( )
-
-Calling `update()` on your Chart instance will re-render the chart with any updated values, allowing you to edit the value of multiple existing points, then render those in one animated render loop.
-
-```javascript
-myLineChart.datasets[0].points[2].value = 50;
-// Would update the first dataset's value of 'March' to be 50
-myLineChart.update();
-// Calling update now animates the position of March from 90 to 50.
-```
-
-#### .addData( valuesArray, label )
-
-Calling `addData(valuesArray, label)` on your Chart instance passing an array of values for each dataset, along with a label for those points.

-The bar chart has the a very similar data structure to the line chart, and has an array of datasets, each with colours and an array of data. Again, colours are in CSS format.

-			 *
-			 * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
-			 *
-			 * Solution:
-			 *
-			 * We assume the radius of the polygon is half the size of the canvas at first
-			 * at each index we check if the text overlaps.
-			 *
-			 * Where it does, we store that angle and that index.
-			 *
-			 * After finding the largest index and angle we calculate how much we need to remove
-			 * from the shape radius to move the point inwards by that x.
-			 *
-			 * We average the left and right distances to get the maximum shape radius that can fit in the box
-			 * along with labels.
-			 *
-			 * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
-			 * on each side, removing that from the size, halving it and adding the left x protrusion width.
-			 *
-			 * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
-			 * and position it in the most space efficient manner
