Hello Luca,
As per my understanding, you would like to know how to delete a ‘ConstantLine’ created using ‘xline’ function in App Designer.
The ‘delete’ function can be used to delete a graphic object such as a ‘ConstantLine’.
Refer to the following sample code for creating and deleting a constant vertical line by changing the state of a ‘StateButton’ in App Designer:
properties (Access = private)
x1 = [];
end
% Callbacks that handle component events
methods (Access = private)
% Value changed function: Button
function ButtonValueChanged(app, event)
value = app.Button.Value
if value
app.x1 = xline(app.UIAxes,0.2,'HandleVisibility','off');
else
if(isprop(app,'x1'))
delete(app.x1);
end
end
end
end
Please refer to the following documentation to know about deleting graphic objects using the ‘delete’ function:
I hope this resolves the issue you were facing.
