Error using ImageLineChart class in GWT

[Shyam Visamsetty]

I get the following error while using ImageLineChart. It works fine
while using LineChart instead of ImageLineChart.

Library version 1.1

Please provide Suggestions.

Thanks,

My first suggestion is that you provide a small sample of code to reproduce the problem - the stack trace is not shedding any light on the problem for me.  We have a demo of ImageLineChart that shows that it works in at least some cases.

Hi Eric,

Thank you for the reply. I was able to resolve the issue. Basically, I loaded the LineChartPackage instead of ImageLineChart package while loading the Visualization API. This issue is resolved.

Thanks,

Shyam.
