3D charts

View example on CodePen

Since 2015 various charts have been updated to have new or improved 3D support. These charts are listed below. Certain visual effects (ie the generic css ones) won't have any issues. Though as with the previous 3D variations, canvas effects (eg the wave effect) may be slowed due to the extra drawing that's involved. As you'll see from the demos there's not a whole lot involved in switching your charts to 3D - just a single configuration property and some increased margin settings (in some cases). There's an example of each 3D style chart listed below.

Example code

This is the example code that goes into making the chart above. The configuration option that makes the chart 3D is highlighted.

<script>
    new RGraph.Bar({
        id: 'cvs',
        data: [ [4,8,3],[5,2,1], [8,4,2],[3,6,1],[5,1,0],[2,5,1],[1,2,2] ],
        options: {
            variant: '3d',
            xaxis: false,
            yaxis: false,
            colorsStroke: 'rgba(0,0,0,0)',
            colors: ['Gradient(#fbb:red)', 'Gradient(#bfb:green)','Gradient(#bbf:blue)'],
            marginTop: 30,
            marginLeft: 45,
            marginBottom: 80,
            shadowColor:'#ccc',
            shadowOffsetx: 3,
            backgroundGridColor: '#eee',
            xaxisColor: '#ddd',
            xaxisScaleUnitsPost: 'km',
            title: 'Distance run in the past week'
        }
    }).draw();
</script>
