options = {
colormap: "jet" // pick your colormap
, nshades: 72 // how many divisions
, format: "hex" // "hex" or "rgb"
}
cg = colormap(options)
where leaving options = {} or undefined results in the defaults given above. There is a minimum number of nshades divisions you can select since the algorithms for each colormap have different requirements. colormap throws an error if there are too few divisions for the chosen colormap and gives the minimum number required. You should be safe with n > 10 for all the colormaps, though some require much less (much simpler to implemenent)."
