[ncl-talk] multiple color markers with single array data (XY plot)

[S Br]

Hi Karin,
I have tried this simple script but still it doesn't work. I can't produce
the markers with different colors.

Thanks.
SB

begin

  x = (/0.205, 0.280/)
  y = (/0.155, 0.050/)

  wks = gsn_open_wks("X11","Test_fig")             ; send graphics to PNG
file

  res                     = True
  res at gsnDraw             = False            ; don't draw
  res at gsnFrame            = False            ; don't advance frame

  res at xyMarkLineModes  = (/"Markers","Markers"/)   ;-- set mark line mode
for both variables
  res at xyMarkers        = (/ 10, 16/)               ;-- choose marker types
  res at xyMarkerColors   = (/"red","blue"/)          ;-- choose marker colors

  plot                    = gsn_csm_xy (wks,x,y,res)

draw(plot)
frame(wks)
end
