# An example of an interactive key

The interactive key was updated in June 2013 and added to more chart types. The types of charts that now support the interactive key are:

- Bar
- Funnel
- Horizontal Bar
- Horizontal Progress
- Line
- Pie
- Radar
- Rose
- Radial Scatter
- Scatter
- Vertical Progress

The interactive key uses the `RGraph.common.dynamic.js` library and the `RGraph.common.core.js` libraries so you'll need to include these in your page if you want your chart to show a dynamic key. Apart from that the only additional property that you need to specify in your chart configuration is this: `keyInteractive: true`.

There's not a lot more going on for this chart except for having angled labels (at 25 degrees) and the groups of bars are made clear by using the `marginInner` and `marginInnerGrouped` properties. The chart also uses the `wave` animation effect.

For smaller screens the text size is reduced, the margins are changed (both the RGraph margins and also the `CSS` margins of the `canvas` tag) and the `CSS` `float` is removed.

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.common.dynamic.js"></script>
    <script src="RGraph.common.key.js"></script>
    <script src="RGraph.drawing.rect.js"></script>
    <script src="RGraph.bar.js"></script>

Put this where you want the chart to show up:

    <div>
        <canvas id="cvs" width="600" height="250" style="float: right; margin-bottom: 50px">[No canvas support]</canvas>
    </div>

This is the code that generates the chart - it should be placed AFTER the `canvas` tag(s):
