<canvas id="cvs" width="600" height="250"> [No canvas support] </canvas>This is the code that generates the chart:
<script> var data1 = [[2,5,9],[4,2,6],[6,5,8]], data2 = [[-2,-1,-6],[0,0,-6],[0,-5,-8]]; new RGraph.Bar({ id: 'cvs', data: data1, options: { gutterLeft: 35, shadow: false, strokestyle: 'rgba(0,0,0,0)', noaxes: true, ylabels: false, colors: RGraph.ISOLD ? ['black','black','black'] : ['Gradient(black:#aaa:black)', 'Gradient(black:#aaa:black)', 'Gradient(black:#aaa:black)'], hmargin: 25, backgroundGridAutofitNumvlines: 3, xaxispos: 'center', 'text.size': 14, ymax: 10, textAccessible: true } }).wave(); new RGraph.Bar({ id: 'cvs', data: data2, options: { gutterLeft: 35, shadow: false, colors: RGraph.ISOLD ?
