BUG: 95020
when more than one data point lies in a pixel, a vertical line is drawn
in that pixel, from the min to max point in the pixel.  If ymin==ymax,
then the line is of zero length.  With linewidth!=0, a 0 length line draws
nothing.  Hence, no line.

This adds linewidth to the length of the vertical line - so something always
gets drawn.
