I do not have a live link to provide as I am behind a firewall. Attached is a very simple example.
The attached zip has 2 html files. Unzip it to any web server (I use tomcat) which has the fusion charts js library. It refers to <script type="text/javascript" src="fusioncharts-321/FusionCharts.js"></script>. Notice the fusioncharts-321. With v 3.2.1, on an iPad (use Safari), when you are on http://<your host>:<your port>/fusionchart.html you can pinch zoom and then drag to scroll the chart. However, if you access the same by simply replacing the fusioncharts library to v 3.2.2, you can still pinch zoom, but you can no longer scroll. It appears that if there is a link specifid on the chart the scroll functionality is lost.
