Is there a way to apply "hold on" to some plot objects, but to apply "hold off" to other objects in the same plot?
The example below plots a pcolor object then several lines. I want the pcolor object to remain plotted as if it were "hold on", but as each new line is plotted, I want the old line to disappear, as if the lines were "hold off". (At the time I wrote this, I thought deleting the line handle h2 was not an option: the real code is buried in a GUI currentpoint function which seems to prevent me from accessing h2.)
figure;
p = peaks;
[nY, nX] = size(peaks);
x = 1:nX; y = 1:nY;
h1 = pcolor(x, y, peaks);
shading flat;
hold on;
title('Wish we could hold pcolor but not lines')
nLine = 10;
for iLine = 1:(nLine)
h2 = plot(rand(1,10)*nX, rand(1,10)*nY, 'ko-');
pause(1);
end
