XY stepped plot: draw an horizontal segment even when there is no Y value
Submitted by Frédéric Parrenin
Created attachment 319329 .gnumeric file to illustrate the problem
The stepped XY plots are often used to display averages over intervals. In this case, there is one less Y value than the X values. It would make sense in these circumstances to display the horizontal segment at the end (step at the beginning) or at the beginning (step at the end). I attach an example .gnumeric file.
