Tooltip fix
2016-03-13 09:29:11 -04:00
David Cochrum a446bf979a Fix multi-dataset bar highlighting
When a bar graph contains multiple data sets and any of the datasets are incomplete (ie: no data yet for April through December of this year), the `activeBar` objects without a data point at that location received by `this.getBarsAtEvent(evt)` are `undefined`. This includes a check prior to attempting to access its properties (lines 86-89).

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.

```javascript
new Chart(ctx).Bar({
