Hi all,
I am contouring data onto a cylindrical map projection using the gun_csm_contour_map_ce function. I would like to adjust the the lat and lon labels to tenths of a degree, but it seems that only whole numbers are allowed (e.g. mpGridLatSpacingF)? Is there a way to label sub-degree?
My 'dBZ' data has coordinate variables with units "degrees_north" and "degrees_east" for lat and lon, respectively.
My plotting code is below.
;==================================================
...
resHor=True
resHor@gsnDraw=False
resHor@gsnFrame=False
resHor@tiXAxisFontHeightF=.015
resHor@tiYAxisFontHeightF=.015
resHor@gsnLeftString=mms+"/"+dds+"/"+yys ; Make own label
resHor@gsnLeftStringFontHeightF=.023 ; Shrink the font size
resHor@gsnRightString=t_start+"-"+t_end+" UTC" ; Make own label
resHor@gsnRightStringFontHeightF=.023 ;Shrink the font size
resHor@gsnSpreadColors=False ; True=Use the full range of colormap
resHor@cnFillOn=True ; Turn on color
resHor@cnLinesOn=False ; Turn off contour lines
resHor@cnLineLabelsOn=False ; Turn off line labels
resHor@cnInfoLabelOn=False ; Turn of contour label info
resHor@cnLevelSelectionMode="ExplicitLevels" ; User defined levels
resHor@cnLevels=clevs_dBZ ; Set contour levels
resHor@lbLabelBarOn=False ; Turn off label bar and plot just 1 for panel
resHor@mpLimitMode="LatLon"
resHor@gsnAddCyclic=False
resHor@mpMinLonF=min(XLon)-(.05*(abs(max(XLon)-min(XLon))))
resHor@mpMaxLonF=max(XLon)+(.05*(abs(max(XLon)-min(XLon))))
resHor@mpMinLatF=min(YLat)-(.05*(abs(max(YLat)-min(YLat))))
resHor@mpMaxLatF=max(YLat)+(.05*(abs(max(YLat)-min(YLat))))
resHor@mpGridLonSpacingF=1. ; Can't get less than 1 degree??
resHor@mpGridLatSpacingF=1.
panID(ii)=gsn_csm_contour_map_ce(wks,dBZ(Zind,:,:),resHor)
