A Line chart with a gradient fill
This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
points = 365 * 2;
data = [];
last = 16;
max = 50;
// Create the data
for (var i=0; i<points; i+=1) {
last = (RGraph.random(-1,1) + last);
last = Math.min(last, max);
last = Math.max(last, 0);
data.push(last);
}
new RGraph.Line({
id: 'cvs',
data: data,
options: {
shadow: null,
filled: true,
filledColors: 'Gradient(rgba(255,255,255,0.5):rgba(0,200,200,0.25))',
xaxisTickmarksCount: 8,
xaxisLabels: [

],

}).draw();
</script>
