I have a google motion chart and I'd like to have a title that dynamically updates if the user changes the quantities displayed. The way I thought I'd do this is by capturing the statechange event for the chart and then using javascript to change the title, for example something like this:
<script type="text/javascript" src="http://www.google.com/jsapi";></ script> <script type="text/javascript"> google.load('visualization', '1', {'packages': ['motionchart']}); google.setOnLoadCallback(function() { ... code snipped here ... var chart = new google.visualization.MotionChart (document.getElementById('divId')); chart.draw(data, config); var onstatechange = function() { alert("chart state changed"); document.getElementById('div_debug').innerHTML = chart.getState(); }; chart.statechange = onstatechange; }); </script> However, this code doesn't do what I expect. I get a very pretty motion chart, but the onstatechange callback function doesn't get called. What should I be doing here?
