The next generation and release of Chart.js (v2.0) has been well under way this year and we are very close to releasing some amazing new features including, but not limited to:
- Rewritten, optimized, and unit-tested
- New and improved scales (log, time, linear, category, multiple scales)
- Improved Tooltips and tooltip callbacks for customization
- Improved responsiveness and resizing
- Powerful support for adding, removing, changing, and updating data on the fly
- Animations for everything, including all elements, colors and tooltips
- Powerful customization when you need it. Automatic and dynamic when you don't.
- Excellent support for modern frameworks and modular build systems.
- Even more extensible via new element controllers, core scale classes, combo chart support, and hook systems
- Bug fixes, stability improvements, etc.
#####Contributing to 2.0
Submit PR's to the v2.0-dev branch.
#####Building and Testing
`gulp build`, `gulp test`, `gulp watch --test`
#####v1.x Status: Feature Complete
v1.x is now considered feature complete. PR's for bug fixes are still extremely welcome. Any open PR's for v1.x features will need to be reconsidered, refactored and resubmitted for v2.x (if the feature has not already been implemented). For questions on new features refer to the docs in the v2.0-dev branch

###Tooltip Templates
For the `tooltipTemplate` and `multiTooltipTemplate` configuration options, you may use special template blocks. **Do not use user input in the tooltip template, as it may be executed as raw JavaScript.**
Anything in between `<%` and `%>` will be executed as JavaScript. As in the example shown above, `<% if (label) { %>` and later `<% } %>`. Using `<%= expr %>` will print the value of the variable named by `expr` into the tooltip.
The available variables to print into the tooltip depends on the chart type. In general, the following variables are available:
```javascript
{
value : "value of the data point",
label : "label for the position the data point is at",
datasetLabel: "label for the dataset the point is from",
strokeColor : "stroke color for the dataset",
fillColor : "fill color for the dataset",
highlightFill : "highlight fill color for the dataset",
highlightStroke : "highlight stroke color for the dataset"
}

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.

You can override these for your `Chart` instance by passing a member `options` into the `Line` method.
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 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.
For example, we could have a line chart without bezier curves between points by doing the following:
```javascript
new Chart(ctx).Line({
data: data,
options: {
xAxes: [{
show: false
}]
}
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.
