Hullo All,
I have been having problems plotting with mesh.
Using gnuplot was taking ages, and I eventually found how to initialise
fltk.
Using fltk is much faster, but I haven't yet been able to get it to do
what I would like.
I have two mesh plots that are generated, firstly as figures, but I would
also like to save these as jpg images, so added print commands.
If I include the print command, the figure is displayed with black
background, no axes etc. and the process brings my systems to it's
knees...everything becomes unresponsive, a condition that continues long
after Octave has been killed.
If I comment out the print, the display is OK, but I have only been able
to get my first figure displayed.
The general form of my code is as follows;
fig1handle = fig+1;
figure (fig1handle);
mesh(x,y,Zabs);
xlabel('x axis');
ylabel('y axis');
print(fig1handle,'results/mesh', '-djpg');
I added the 'fig1handle' to the print command later. The help for 'figure'
doesn't really talk about that function returning a handle, so I probably
don't have this correct. Regardless, it was not working correctly prior to
the the handle being added.
What is the recommended way to display and print a figure using fltk?
I may not be invoking fltk correctly. All I could find on this was some
early notes that say one should use backend("fltk"), but Octave baulked at
that, then later found some words Ben Abbot had writ advising to use
"graphics_toolkit fltk" to initialise the fltk. I currently have this
command early in my script.
What is the recommended way to set up Octave to use fltk?
Is there an up to date guide on using fltk that I could use to come up to
speed?
Cheers,
