Hi,
i'm building a GUI where I'm supposed to turn on or off the Visibility of multiple plots.
So far, what i'm doing is to get the handle of the plot and then toggle the Visibility property.
hraw=plot(cur_axes,time(1:test_plot_range),raw_signal(1:test_plot_range),linetype);
hraw.Visible='on';
For the majority of the plots, i get a handle [1×1 Line].
However, there are cases where the returned handle consists of all the line points [1041×1 Line].
hraw_mean=plot(cur_axes,cur_struct.time(1:test_plot_range),raw_mean*ones(test_plot_range),'m-','MarkerSize',cell2mat(signal_struct.params(4)));
Please note that "hraw_mean" refers to a straight line, where the "hraw" handler refers to random signals (not straight lines).
A workaround would be to loop through all points and toggle their visibility ( indexing with : -e.g. hraw_mean(:) raises an error), but I'd prefer a more elegant way (i.e. return a single sized handler).
Are there any suggestions?
Thank you in advance
Markos

You can use set function.
hraw_mean.set('Visible','off');
That sets Visible proptery of all cells to off. If you want to set a property for some cells only.
hraw_mean([1:3 7 8]).set('Visible','off');

It is because of your input data. ones(size) gives you sqare matrix of dimension size X size
raw_mean*ones(test_plot_range)
Generate 1D array instead
raw_mean*ones(1,test_plot_range)
