HOWTO: Use CSS 3D transformations

Example

Here's an example of the code below that shows a 3D Line chart

[No canvas support]

Introduction

WebKit (which is used by Chrome, Safari, Edge, Opera and possibly others) and Firefox all support CSS 3D transformations. If you're tasked with supporting these browsers then by using 3D transformations you can add 3D effects to your charts. The effect is specified by adding a CSS property which is shown below. Because the effect changes the position of the canvas coordinates in relation to the page you must also tell RGraph to position the tooltips at the pageX/pageY coordinates which you do with the tooltipsCoordsPage option - as shown below. 

<canvas id="cvs"
       width="600"
       height="250"
       style="-webkit-transform: rotate3d(0, 1, 0, 45deg) rotate3d(0, 0, 1, 5deg) rotate3d(1, 0, 0, -15deg);
              -moz-transform: rotate3d(0, 1, 0, 45deg) rotate3d(0, 0, 1, 5deg) rotate3d(1, 0, 0, -15deg);
              -o-transform: rotate3d(0, 1, 0, 45deg) rotate3d(0, 0, 1, 5deg) rotate3d(1, 0, 0, -15deg);
              -ms-transform: rotate3d(0, 1, 0, 45deg) rotate3d(0, 0, 1, 5deg) rotate3d(1, 0, 0, -15deg);
              transform: rotate3d(0, 1, 0, 45deg) rotate3d(0, 0, 1, 5deg) rotate3d(1, 0, 0, -15deg);
              box-shadow: 3px 3px 5px gray">[No canvas support]</canvas>
<script>
    new RGraph.Line({
        id: 'cvs',
        data: [4,6,8,4,1,3,4,2,8],
        options: {
            xaxisLabels: ['John', 'Lou','Kevin','Barry','John','Alex','Nick','Fred','June'],
            tooltips: '%{property:xaxisLabels[%{index}]}',
            tooltipsCss: {
                fontSize: '20pt'
            },
            tooltipsPositionStatic: false,
            tooltipsCoordsPage: true,
            marginInner: 10,
            tickmarksStyle: 'filledarrow',
            tickmarksSize: 15,
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            xaxis: false,
            yaxis: false,
            textSize: 16,
            spline: true
        }
    }).draw();
