How can I get rid of the gap in the category axis?

Hello

I have simple line chart. In the X axis normally I would expect that the first series element starts directly on the left end of the X axis. But there is always a gap that I cannot get rid of. I tried to adjust with Padding parameter, but didn't help.

What could I do else?

This would happen if the category data type is string instead of a numeric type. Try changing it to a numeric type.
