I don't know how to directly get the number of colors
without opening a workstation.
If someone does ... please respond.
---- Here is one approach: wks = gsn_open_wks("x11","test1") gsn_define_colormap(wks,"BlWhRe") cmap = gsn_retrieve_colormap(wks) dimc = dimsizes(cmap) nMax = dimc(0) ; max colors For BlWhRe, it would be nMax=103 Hence, the start/end indices would be 2,102(=nMax-1) You could create a function. function getNumberColors (wks:graphic] begin cmap = gsn_retrieve_colormap(wks) dimc = dimsizes(cmap) nMax = dimc(0) ; max colors return(nMax) end Kai Zhang wrote: > Dear all, > > Is there a function which can tell me the beginning and ending index > of a certain color table? I know that we can look it up on the NCL web > site, but it is always nice to let NCL do it automatically.
