Hi,
What I am doing is to use the indexes of the QlistWidget box:
for ListIndex in QListWidget
idx=ListIndex.row()
idx is an index (you need to create the proper one) to go through the data
stored in the variable which is the feed for my QLIstView
Then you can loop using your index through your data and plot them just
including the .plot(x,y[idx]) in the loop
