I need to set a callback for when data in axis is updated. Is there a way to do this? i.e is their a way to be notified when a figure/axis/line data changes.
Thanks

fig = figure;
ax1 = axes(fig);
h = plot(ax1, randn(1001,1));
addlistener(h, 'YData', 'PostSet', @(~,~)disp("YData changed!"));
% Changing data...
h.YData(1) = 2*h.YData(1);
% Answer:
% "YData changed!"
