We are sorry to hear that you were not able to create Horizontal Bar Series even with the information provided in our documentation. I attached a sample project that demonstrates how you might achieve this (click on the checkbox on the demo to see how the Bar Series change from Vertical to Horizontal).
Feel free to review the code and modify the project per your own scenario needs.
As for the UI for WPF launcher and the strange majic.dll that you mentioned - I'm not sure where and how you come upon such assembly.
In fact there is an online demo with full source code provided that shows how to change the Bars from Vertical to Horizontal - here
is link to it. Use the checkbox in the Configuration Panel on the Left to switch to Horizontal Bar Series.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
