Plot handle to return single object

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

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');

Thank you for your answer.

This does the work but still I'd prefer to get a [1x1 Line] handle for all cases. Is it possible?

And I still wonder: why in the first case I'm getting a 1x1 Line while in the second a 1041x1 Line handle?

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)

You're so right.

Thank you very much.
