From the gnuplot help:

The new syntax is to simply place the limits in opposite order. So I replaced

with

and obtained the proper plot.

I set about fixing this then discovered I already made a changeset, attached here:

https://savannah.gnu.org/bugs/?38914

BTW, just curious if you think the axes would look better for this plot if the x-axis were at the top of the plot rather than at the bottom. If I were to illustrate the indices of a matrix, I think that's how I would do it:

Thanks for your bug report. Confirmed on Debian with gnuplot 5 as well, works correctly as before with gnuplot 4.6.6.

OS: Arch Linux
Octave version: 3.8.1
gnuplot version: 5.0.0

"Spy" with gnuplot shows the matrix upside-down (last row on top, first row at bottom). The problem doesn't show up with fltk. It seems to be due to the interaction with gnuplot. With gnuplot version 4.6.6, the plot is correct.
