Plot two sets of markers in GUI

Hi,

I am creating a GUI. It displays a graph and marks a few indexes using plot and markers (upper image). now I want to mark again some of the previous indexes, but when I try to do so - all the first markers are deleted.

this is the first plot of a graph + markers:

"plot(handles.axesNS1, handles.sigNV(:,1), handles.sigNV(:,2), '-*','MarkerIndices', handles.presentedRRNS1, 'MarkerEdgeColor','red', 'MarkerSize', 6)"

It works fine and plots red markers (upper image). then I add the following command in the next row:

"plot(handles.axesNS1, handles.sigNV(:,1), handles.sigNV(:,2), 'o', 'MarkerIndices', handles.Missed_NS1, 'MarkerEdgeColor','black', 'MarkerSize', 7)"

and it deletes all red markers and displays just the black ones. (lower image)

how can I display this graph with both groups of markers one on each other?

Note: when I use the same method outside the GUI - it works fine and both markers appear.

Use hold on or its equivalent: set the NextPlot axes property to 'add'.

try

hold(handles.axesNS1,'on')

So if you use this:

plot(handles.axesNS1, handles.sigNV(:,1), handles.sigNV(:,2), '-*','MarkerIndices', handles.presentedRRNS1, 'MarkerEdgeColor','red', 'MarkerSize', 6)
set(handles.axesNS1,'NextPlot','add')
plot(handles.axesNS1, handles.sigNV(:,1), handles.sigNV(:,2), 'o', 'MarkerIndices', handles.Missed_NS1, 'MarkerEdgeColor','black', 'MarkerSize', 7)

that still results in the wrong result?
