This HProgress chart doesn't use the built-in adjusting but uses a cutom onclick event listener (which you can see below) in order to make the adjusting animated.
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.hprogress.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="100">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
new RGraph.HProgress({
id: 'cvs',
min: 0,
max: 100,
value:89,
options: {
tickmarks: 100,
numticks: 20,
gutterRight: 30,
margin: 5,
textAccessible: true
}
}).draw().exec(function(obj)
{
obj.canvas.onclick = function (e)
{
var value = obj.getValue(e);
obj.value = value;
obj.grow();
}
});
</script>
