QuoteI solved that problem
How?
The first row is the number 0, why would you expect coordinate 0 to be out of the target?
So the problem is that your Y-axis primitive is not shown, actually.
You should avoid integer coordinates when you draw lines. If you want a 1-pixel wide line that fills the first row or column of pixels, ie. the range [0, 1], it's coordinate must probably be 0.5 since it represents the "center" of the line.
Try this and let me know if it solves your problem.
