We are not aware of the mentioned issue.
Could you please provide us with more details on the matter:
- If you are not using latest Telerik UI version - 2015.1.225, does upgrading to it helps?
- It may be possible that you are plotting many items on the chart so it gets some time to render them. Please refer to the Performance Optimizations
help article for details on the matter.
- Do you reproduce the issue with our online demos
and if so which is the demo/demos?
- Can you provide us with a small runnable sample that reproduces the issue?
I have also converted the type of this thread to RadHtmlChart for ASP.NET AJAX as the title states it.
