[Octave-bug-tracker] [bug #51772] Errors when running compare_plot_demos with gnuplot toolkit on Windows

[Avinoam Kalma]

Follow-up Comment #1, bug #51772 (project octave):

A simple example:


graphics_toolkit gnuplot
demo ("axis", 5);
print ("-dpng", "a5.png");
demo ("axis", 6);
print ("-dpng", "a6.png");


The result on Win-7 machine with dev version is:


>> bug_71772
axis example 5:
 clf;
 x = 0:0.1:10;
 plot (x, sin(x));
 axis image;
 title ({"image", 'equivalent to "tight" & "equal"'});

         line 0: warning: Terminal canvas area too small to hold plot.
            Check plot boundary and font sizes.
axis example 6:
 clf;
 colormap ("default");
 [x,y,z] = peaks (50);
 x1 = max (x(:));
 pcolor (x-x1, y-x1/2, z);
 hold on;
 [x,y,z] = sombrero ();
 s = x1 / max (x(:));
 pcolor (s*x+x1, s*y+x1/2, 5*z);
 axis tight;

The process cannot access the file because it is being used by another
process.


This happens in dev version, but not in 4.2.1, so it is marked as regression
