plot - In Matlab: When plotting in 3d, using colormap(..), how to specify 'transparent' (white?) color for the value 'zero'? -

-

in matlab:

when plotting in 3d following: 

xxxxx=normrnd(1,1,[1,10000]); yyyyy=normrnd(1,1,[1,10000]);  minx=min(xxxxx); maxx=max(xxxxx); miny=min(yyyyy); maxy=max(yyyyy);  x = minx:(maxx-minx)/10:maxx;  y = miny:(maxy-miny)/10:maxy;  [x,y] = meshgrid(x,y);  hist3 = hist3([xxxxx' ,yyyyy'],{x y});  figure();  surf(x,y,hist3);  colormap(jet);  shading interp;

is possible specify 'transparent' (white?) color surface @ 'zero' (instead of dark blue, seen if plot code above)?

thanks on advance!

instead of use "jet" built-in colormap, can define custom colormap first value white (1.0 1.0 1.0 in rgb think) in matlab page. example wrote is

map = [0.2, 0.1, 0.5  % fisrt color     0.1, 0.5, 0.8     0.2, 0.7, 0.6     0.8, 0.7, 0.3     0.9, 1, 0];  % last color

in each line rgb color. every value 0.0 , 1.0 , not 0 255.
