Hi,
By default, the range of ColorData["GrayTones"] is {0,1} such that 0 is black and 1 is white. I would like to change this range from {-10,10} (say). So, -10 is black and 10 is white.
I've tried ColorDataFunction[{-10, 10}, ColorData["GrayTones", "Panel"]] which returns a good results in a notebook, but when I try to plot something like this :
Export[prefix <> ".snapshot." <> snap <> ".vz." <> colorscheme <>
".png", ListDensityPlot[datavz, AspectRatio -> Automatic,
Axes -> False, ColorFunction -> ColorDataFunction[{-10, 10}, ColorData["GrayTones", "Panel"]],
Frame -> False, PlotRange -> All, ImageSize -> Large]];
I get the following error :
RuleDelayed::argr: RuleDelayed called with 1 argument; 2 arguments \
are expected. >>
ListDensityPlot::color: ColorDataFunction[{-10,10}...is not a valid color or gray-level specification. >>
So, how do I change correctly the range of any color scheme in order to plot (here ListDensityPlot) something ?
Thank you by advance for your help,
Florent
