Hello dear support. I am with the latest version and for sure it does not works at all correctly after the first time the button is clicked.
The bug is reproduced on all versions of the components we had, including the last one, on all devices we have have, on all Visual Studio's we have compiled, on 3 different version of IIS, and on Chrome, Firefox and Edge - all of them tested on 4 different computers.
The reproduction as I have mentioned requires to click a few times the button. The first time is fine, but after then - the chart stops to render one or another element, and the even the timeline start to mess up.
