[ncl-talk] Just a note on markid (adding names, symbols to plots)

[Barry Lynn]

Hi:

I didn't see a recent note on this, but it still may confuse at least some
people.

When you want to plot multiple frames on a page, with city names and
markers, you need to set a unique marker set for each frame.

Here is how you do it.

  text_name = new((/n_plots,ncities/),graphic)   ; Create array to hold
text objects

  mark_name := new((/n_plots,ncities/),graphic)   ; Create array to hold
marker objects


where n_plots is the number of frames, maps on a page.


  text_name(i_plot,:) = gsn_add_polymarker(wks,plot_ov,lon,lat,mkres)

  mark_name(i_plot,:)= gsn_add_text(wks,plot_ov,cities,lon,lat,txres)
