Hello,
I try to do animation in Octave and have trouble with animation.
My aim is to draw objects without deleting/erasing the old drawings (but I
do alter the graphics). My attempt is to set "erasemode" - "none" which
sounds promising but doesn't work.
However, in the end I do not get several lines plotted but only one at each
step.
My simple test code:
val = [1 1 2 2]
h = line(val(1:2),val(3:4),'linewidth',5,'color','r'); hold on;
axis([-50 50 -50 50])
set(h,'erasemode','none');
for i = 1:10
val([1,3]) += [1,4];
val([2 4]) -= [2,1];
set(h, 'xdata', val(1:2), 'ydata',val(3:4))
pause(1);
drawnow;
endfor
Thank you for your help :)
