[ncl-talk] How to coincide zero with the white color of the colo bar with uneven numbering

[mamadoulamine.mbaye at ucad.edu.sn]

Hi Tirkey,

You can use   res at cnFillColors   = (/put the numbers corresponding of the desired color:

https://www.ncl.ucar.edu/Document/Graphics/ColorTables/BlueWhiteOrangeRed.shtml /)

Each color should has a number

Hope this helps!

Mamadou,

Regards

Objet : [ncl-talk] How to coincide zero with the white color of the colo bar with uneven numbering

Hello NCL users,

I am trying to plot a color plot with a color bar of range -1 to 2 with an interval of 0.2 by using-

  wks = gsn_open_wks("ps","MSE_0.5")
  gsn_define_colormap(wks,"BlueWhiteOrangeRed")

  res               =  True
  res at gsnMaximize      =  True
  res at gsnAddCyclic     =  False
  res at cnFillOn           =  True
  res at gsnSpreadColors  =  True
  res at gsnSpreadColorStart = -1
  res at gsnSpreadColorEnd  = 2
  res at trXMinF        = 11
  res at trXMaxF        = 27
 res at cnLevelSelectionMode =  "ManualLevels"
  res at cnLevelSpacingF    = 0.2
  res at cnMinLevelValF   =  -1
  res at cnMaxLevelValF    = 2

I want '0' to coincide with the white of the bar but it is coinciding with the yellow. Please help.

Thanking in anticipation.

Yours sincerely,
Snehlata Tirkey
