Hi,
I would like to overwrite only the data presented in a figure while keeping the labels and legends the same. I do not want to waste space and time on re-labeling the figures. 'hold on' holds the plot but does not overwrite the existing data and only adds to it.
Thank you for your help.

h=plot(rand(1,100));
title('random signal');
legend('blue signal');
set(h,'XData',1:10,'YData',1:10);

Hi, you can use
hold on
cla
plot(newData)
cla (clear all) will remove the plotted data but not other formatting.

I don't see how the previous answer keeps the axis labels, title and legend when plotting some new data on the same axis.
The code that worked for the author (and for me) was:
title('Some Title','HandleVisibility','off');
ylabel('Some ylabel','HandleVisibility','off');
xlabel('Some xlabel','HandleVisibility','off');
set(gca,'NextPlot','replacechildren') ;
Any subsequent plots on this axes keeps the existing axes properties (including title, axis labels and legend), while replacing child objects (e.g. data)
