xAxis Renderer label

[EvaOyy]

What did you do?

I would like to use NSRange in my overriden drawLabel function to further attribute my label String

What did you expect to happen?

I expect my label , for example "NorthSouth" to have the part "North" bolded and "South" with the normal font

What happened instead?

I cannot format my label this way as we can only work with String and NSAttributedString separately in this function
