This version features preliminary support for native chart GUI (buttons and edits at the moment). Please be reasonable with Gui* functions and be aware of Windows limits. As all controls in Windows (buttons, edit boxes, etc) are actual Window objects they are subject to Windows limitation. And there is a limit of 10000 windows PER PROCESS. So don't try to create thousands of buttons (like a button for every bar of data) because first you will see huge performance decrease and next you will hit the limit and run into problems (crash), see

Best practice is to keep the number under 100-200. If you need more consider using low-level graphics instead.
