Hello deyvi,
I am checking about the progress of this issue. Please let me know If you need any further assistance on this.
I was not able to understand anything from your post except that you are using the WinChart control. Could you please try to explain again and format your post? What is your scenario, what is the exact version of 10.3 that you are using? Could you please attach a small sample project which demonstrates the issue and let me know of the setup I need to use in order to reproduce it?
I will be waiting for your feedback.
