A basic example of the drawing API circle object
This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.drawing.circle.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>
line = new RGraph.Line({
id: 'cvs',
data: [5,8,6,4,3,5,2],
options: {
marginInner: 5,
xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
}
}).draw();
coords = line.coords[2];
circle = new RGraph.Drawing.Circle({
id: 'cvs',
x: coords[0],
y: coords[1],
radius: 30,
options: {
colorsStroke: 'black',
colorsFill: 'red',
linewidth: 3,
tooltips: ['Hurrah!']
}
}).draw();
</script>
