[ncl-talk] How might I keep the map size constant?

[Barry Lynn]

Hi Rick:

I have implemented this and hopefully it will solve the problem.

Thank you!

 Title = time_var + " strokes = " + sum_light

  res at gsnFrame        = False

  plot_t    = gsn_csm_contour_map(wks,terrain_only,res)   ; create the
terrain plot

; txres               = True                     ; already defined.

  txres at txFontHeightF = 0.027

; page coordinates are normalized. go from 0->1 not 0->8" etc.

  gsn_text_ndc(wks,Title,0.04,0.96,txres) ; text appears at the top of the
mapped page.

  txres at txFontHeightF = 0.010 ; reset back to original value for city names.
