Marker Styles
There are 17 predefined markers available. You can change the marker style by using gsMarkerIndex for markers associated with polymarkers or gsn_add_polymarker, gsn_polymarker, gsn_polymarker_ndc.For scatter plots or xy plots that include markers in addition to lines, use xyMarker or xyMarkers(more than one line on a plot).
The marker style is changed using an integer from 0 to 16. The default is marker index 0 (Asterisk).
You can also make your own marker style using the NhlNewMarker function. See XY application example 4.
