[ncl-talk] Polyline not displaying

[Kacie Shourd]

Ok, so I added a couple of lines to your script (new version attached; with comments so you can easily identify new lines):

       radres at gsnFrame = False

added to your plot resources, and then

       frame(wks)

after adding the polyline on top of your plot (I also changed "PreDraw" to "PostDraw" so that the line goes on top of your contours).

Let me know if this works! If not, we can similarly add "gsnDraw = False" and "draw(plot)" where needed, but I think the changes made should do the trick.

Best,
Kacie

Hey Kacie,

Yup, tried that.  That was my first thought.

Here's the whole script (attached), if it helps.

Thanks,
Ryan

Hiya Ryan,

Have you tried changing
  gres at cnLineDrawOrder      = "PreDraw"

to

  gres at cnLineDrawOrder      = "PostDraw"

??

Without seeing more of your script or your output that's all I can suggest!

Best,
Kacie

Hi,

I added this small section to the bottom of a script:

plot =  gsn_csm_contour_map(wks,rd_plane,radres)

; Construct a polyline to show cross-section location

  gres                 = True
  gres at gsFillColor     = "black"
  gres at cnLineDrawOrder      = "PreDraw"
  gres at gsLineThicknessF     = 5.0

  lat = (/44.4,  42.9/)
  lon = (/-71.3, -69.3/)
  dum = gsn_add_polyline(wks,plot,lon,lat,gres)

  draw(plot)


But can't seem to get the line to appear.  Can anyone tell me what I'm doing wrong?

Thanks,
Ryan
