If I read your correctly,
for l, b in zip(x, y):
# And here I work with data coordinates (!)
dashBox = Bbox.from_bounds(l, b, width+5, height+5)
badness = 0
for line in lines:
if line.intersects_bbox(dashBox):
badness += 1
x, y (therefore l, b) in data coordinate.
width, height?? this seems to be some wx specific coordinate, i have no idea.
lines (therefore line) in display coordinate.
converting x,y to display coordinate should straight forward. But I'm
not sure what kind of coordinate width and height has. Is it a method
of some class derived from matplotlib's Text?? If then, the extent of
the text can be measured using the get_window_extent method. This
requires a renderer instance, which should be known if the method is
called during the drawing time.
Again, post a complete but simple(!) code.
