I have tried to reproduce the mentioned issue with the provided code snippet but to no avail. You can see the chart's output here.
I can suggest that you try the following steps:
- If you are not using the latest Telerik UI version - 2014.3.1024 does upgrading to it resolve the issue?
- It may be possible that some global styles are affecting the appearance of the chart. Does removing all of the custom CSS resolve the problem? If that is so you can start turning one by one the styles until you find and fix the problematic one.
- Decrease the width and height of the chart and set a negative value for the PlotArea's margin. For example:
<TextStyle Margin="-30" />
If the above steps, however, do not help could you please try to reproduce the unexpected behavior with the attached archive and then tell us what changes you have made, so that we can proceed further with the investigation?
