Make lines visible or invisible

Is there a way (in a script) to make lines visible or invisible when you open a figure already existing (using openfig())? Thanks

Answer 1

plot(rand(10,1))
set(gcf,'visible','off')
set(gcf,'visible','on')

Answer 2

There is:

t = 0:0.1:10;
y = sin(t);
figure
h1 = plot(t,y);
set(h1,'Tag','Line1')
hold on
h2 = plot(t,y.^2);
set(h2,'Tag','Line2')

savefig('MySavedPlot.fig');
close(gcf)
clear

fig = openfig('MySavedPlot.fig');
axesObjs = get(fig, 'Children');
dataObjs = get(axesObjs, 'Children');
set(findobj(dataObjs,'Tag','Line2'),'LineStyle','none');

It works also if you have more than one line? Because I have a graph with 14 lines and I would like to make visible all the combination of 2 lines and save all the "2 line graphs" as *.emf file.

[Mischa Kim]

Yes, it is: tag all 14 lines so you can find them again using the findobj command. See updated script above.

Is there a way to do this but still have the original color show up in the legend. I want to have a correct legend corresponding to conditions but if the plot doesn't meet all of them I don't want to plot it.

@Devlin Murray were you able to figure out how to do what you asked? I'm trying to do the same thing, thank you!
