Click items in the legend to show or hide the associated line in plot

Hello everybody,
To start with an example will be easier for me, so lets assume that
I have 3 files all of them include some x values and some y values.
x axis is for frequency (i.e 8 to 10 GHz)
y axis is for epsilon corresponding to its frequency
I want to compare epsilon corresponding to its frequency of these 3 files by plotting the data. Files are formatted as *.csv.
Basically I use plot function with hold on command.
figure
plot(freq,eps1);
hold on;
plot(freq,eps2);
plot(freq,eps3);
xlabel("Frequency [GHz]"); ylabel("\epsilon")
legend("eps1","eps2","eps3")
Which gives me normal plot. What I want to do is that when you click the "eps2" on the legend for example, hide the line from the graph and only compare eps1 and eps3. And also to show the hided line, click to its legend name again
I use rfplot with VNA data's and that plot type has this kind of feature for sparameters plot.
Can we use this feature for any plot function?

freq = 1:10;
eps1 = rand(10,1);
eps2 = rand(10,1);
eps3 = rand(10,1);
figure
plot(freq,eps1);
hold on;
plot(freq,eps2);
plot(freq,eps3);
xlabel("Frequency [GHz]"); ylabel("\epsilon")
legend("eps1","eps2","eps3",'ItemHitFcn',@cb_legend)
function cb_legend(~,evt)
if strcmp(evt.Peer.Visible,'on')
evt.Peer.Visible = 'off';
else
evt.Peer.Visible = 'on';
end
end

Thanks a lot.
That is pretty easy and cool. Is there a setting to hide all lines exept mayby the first one by default?
Kind regards Christoph

Ok, got it.. You have to set the visibilty of the plot to "off"
like
plot(freq,eps2,'Visible','off');
