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>
