i have a field in which i plot something. as soon as i click on a button the code is executed.
plot(app.UIAxes3,track,bottomLine,'r',track,topLine,'g');
hold(app.UIAxes3,'on')
plot(app.UIAxes3,track,-bottomLine,'r',track,-topLine,'g');
now i would like to plot a vertical line over it, which i move from left to right depending on a variable change. Without always replotting the image. Is that possible?
the image should only be replotted when I press the button again
Thanks

You can plot the line using xline() and then merely update it's Value property to move it. The line's handle must be stored as an app property.
2) Plot the line somewhere in your code (a callback function or at startup) and store the handle.
app.verticalLineHandle = xline(app.UIAxes3, 0); % this plots the vert line at x=0
3) In your button callback function, all you need to do is change the value of the line to move it.
app.verticalLineHandle.Value = 1; % Now the line is at x=1

Yes, that's the correct way to implement it.
A line will be produced every time you call the xline() function. So, only call that once. Then update the xline value as needed.
To delete the line,
delete(app.verticalLineHandle)
