I am getting problem due to y axis label.
You can see due to tezt size chart becomes small.
So how wrap text?
The image doesn't seem to be appearing on your post.
Could you try posting the image again?
This would really help me understand the issue you're describing.
Kind Regards, Andrew Polkinghorn
This isn't something we currently support. Have you thought about having a shorter text value for your labels? You could then try adding a gesture recognizer to your labels via the alterTickMark: delegate method, and then present a popover with the labels full text when the user taps it?
I've raised this as a feature request in our backlog and we'll consider your request when it comes to implementing new features.
