Hi folks,
I have the following code for generating 1 or multiple plots on an image.
function ROI(app, index1, index2)
hold (app.Image, "on")
plot(app.Image, index1, index2, app.innerMarkerStyle, 'LineWidth', app.CrosshairThickness.Value, 'Color', app.crossHairColour, 'MarkerSize', app.CrosshairRadius.Value);
plot(app.Image, index1, index2, app.outerMarkerStyle, 'LineWidth', app.CrosshairThickness.Value, 'Color', app.crossHairColour, 'MarkerSize', app.CrosshairRadius.Value);
end
My question is, suppose there are 3 such plots. Is there a way to delete 1 and only 1 of them selectively?
Thanks

If you capture the chart line object for each plot, you could use that with the delete function to remove just that line from the plot.
btw, it's best practice to always pair hold on with a corresponding hold off.
Here's a simple example.
% Create a plot with 3 lines
a=plot(rand(1,5));
hold on
b=plot(rand(1,5));
c=plot(rand(1,5));
hold off
% Now delete one of the lines using the line object
delete(b)

No need to apologize. This is no beginner app!
