Hi Angshu,
We are using FusionCharts XT(v3.2.2) (20th September, 2011).
The XML and FusionCharts files are hosted on the Windows 2003 Server. The page that the charts are displayed on is accessible only via a Juniper MAG Series SSL VPN Gateway.
I have attempted visiting the page on using XP, Vista, and Windows 7 using IE7, IE8, IE9, Chrome and FireFox.
The page loaded perfectly in Chrome v14. When Chrome v15 was released, the bar charts turned black. We made no changes to our code.
Thanks,
Christopher A. Eirich
