using cla in a for loop
显示 更早的评论
I am trying to use the cla function to periodically clear my plot durring a for loop. The first set of data plot fine but once i call the cla function nothing else will plot for the remainder of the for loop. what can i do?
for i = 1:4:L
a = rem(i,1201);
if a == 0
cla
end
addpoints(h(1),U(2,i),U(3,i),U(4,i));
addpoints(h(2),W(2,i),W(3,i),W(4,i));
addpoints(h(3),R(2,i),R(3,i),R(4,i));
drawnow
end

When you call cla it removes everything in the axes, including the animated line. The you try to use addpoints to add points to that line... which no longer exists! Clearly this will not work.
Rather than cla perhaps you should try clearpoints: this removes the points from the line, but the line still exists (so you can add new points to it).
