Update of bug #49130 (project octave):
Item Group: Regression => Incorrect Result
Status: Confirmed => None

Follow-up Comment #2:
There are probably multiple problems here. A simple test example for logical
inputs, i.e., black and white is.
close all
graphics_toolkit gnuplot
I = (rand (64,64) >= 0.5);
imshow (I)
A test case for uint8 input is
close all
graphics_toolkit gnuplot
I = uint8 (255*rand (64,64));
imshow (I)
In each case, I get an all white plot with gnuplot 5.0.1. With gnuplot 4.6.6
I get an all black plot. This is for tip

Correct gnuplot toolkit color processing for patch edgecolor (bug #49108)
If I use Octave 4.0.3, I still don't get the correct result if I use gnuplot
5.0.1, but gnuplot 4.6.6 now works.
