MATLAB: Delete a specific shape of marker from a plot

deleteguide

Hello, I am plotting data using dots and then superimpose a marker of type '+' at certain locations. Is it possible to delete just the '+' markers from the GUIDE axes.

I have tried

delete( findobj(gca, 'type', 'line') );

But this deletes all the markers (including '.')

Thanks

Jason

MATLAB: Gca.XLimMode does not work

If you check the xLimMode after running your code, you will see that it has changed back to auto after the plot() statement. You need to hold() the axis to stop it from changing automatically.

fig = figure;
ha1 = axes;
ha1.Position = [0.5 0.5 0.3 0.3]
ha1.XLim = [-10 -5];
ha1.YLim  = [-5 -1];
set(ha1,'xlimMode','manual');
set(ha1,'ylimMode','manual');
[x,y] = ginput;
hold(ha1);  %<--- this line will prevent automatic changes.
plot(x,y);
