hide legend for certain curves in a Matlab plot

Hello everyone,
I have a little problem here, i plot 8 different curves on a figure but i want to hide the legend for the four last of them since they are only the new step of my simulation, does anybody has an idea to keep the legend for the first of them but hide it for the 4 last ones

If you aren't fussed about actually doing this within the code then you can select the lines, open up the property editor, find the property called "Handle Visibility" and set this to "Off".
If you want to do this in your code then you can insert 'HandleVisibility','off' instead of 'displayName','' in the plotting commands of those lines you don't want labelled.
I think that should work! If not then comment back on here and let me know.

Could you give some more information about what exactly you are doing and where it fails (any error messages or strange behaviours, etc.)? That'll help me to see where this isn't working for you.

@ME Thanks it works:
plot(app.UIAxes,X,Y1,'HandleVisibility','off')
plot(app.UIAxes,X,Y2,'DisplayName','Exp')
legend(app.UIAxes)
This hide the curve in the legend for Y1, but add legend 'Exp' for Y2.
Perfect
