Hi again,
(Yeah I know it's my second topic today)
I have another problem.
I try to do a StepLine graph with 2 Y value possible 0 or 1. Primary Y axis is displayed with a margin, primary X axis is not visible.
I work good except when the value is 0 the border of graph area hide the value. In the 1st picture, the border width is 1 and the line width is 2 so we can see a bit of the line but in picture 2 the line width is 1 so we can't see it.
I have a work around who consist in setting Y axis range with -0.01 to 1 but it's not a good solution and we can see a little bit of axis under the 0 tick what is not beautiful.
I can keep it like this but if a better solution exist, I take it.
Thanks to all the people who will help me.
