If you are considering a DICOM-type ROI with multiple contour segments (some of which are holes), you can draw this with a pg.PlotDataItem. You can "chain" together segments of an ROI with holes by inserting a (numpy.inf,numpy.inf) point in between the segments, and setting the "connect" option to connect = 'finite'.
