Thank you for the information.

Although you did not specify the operating system, but I have tested this on XP and Vista, both with user control and main form, and I haven't seen the behavior you have described.

- What Operating system and platform (32-bit, 64-bit) do you have? - 32bit

- What version and specific build of the control you are using? - 2007 Volume 2   & Build Version: 7.3.20073.38

- What type of data source you have bound to the chart? datatable with in this 4 columns & multiple rows

 - Is the chart renderred directly on the form, or from a user control? both , some cases directly on form & from user control

Can you provide more information?
