Suppose I have multiple plots containing various data.

One such plot may be

x = linspace(0,2*pi,1000)
data = sin(2*x) + cos(5*x)
plot(data)

In the GUI, I would now like to select multiple single points or mark multiple segments of the graph, save the indices of the marked data programmatically, and then move to the next plot.

I have tried using brush, but it will only allow me to highlight a single segment. When I want to highlight the next segment, the first segment will not be marked anymore. I also looked into ginput, but it does not allow me to select actual points on the graph. I have thought about creating data tips in the GUI and then storing those, but since the plot contains a lot of points, these are hard to create for me.

Does anyone know if there is a kind of "hold on" function for the highlighting using brush or is there another way to acheive my goal?

Thank you in advance!
