[Octave-bug-tracker] [bug #38961] print freezes when printing certain fplots

[Ben Abbott]

Update of bug #38961 (project octave):

                Category:   Plotting with gnuplot => Plotting

Follow-up Comment #4:

I've changed the category as this also occurs for OpenGL plotting.

I tried the example in Matlab R2013a.  Matlab's fplot() limits the number of
points to 111 for this example to 111.


fplot ('x^2*sin(x)+1', [-2, 2]);
size (get (get (gca, 'children'), 'xdata'))
ans =  1   111



figure (1)
fplot ('x^2*sin(x)+0', [-2, 2]);
size (get (get (gca, 'children'), 'xdata'))
ans =  1   111


I've included two more examples for reference.


fplot ('sin(x)', [-2, 2]);
size (get (get (gca, 'children'), 'xdata'))
ans =  1   179



fplot ('x', [-2, 2]);
size (get (get (gca, 'children'), 'xdata'))
ans =  1   10



fplot ('1/x', [-2, 2]);
size (get (get (gca, 'children'), 'xdata'))
ans =  1   176


I can run additional examples if it is helpful.
