How can I represent my image pixel values inside a HSV cone

Hello,
I'm trying to develop a colour model for fire in HSV colour space.I have a million sample pixels per channel for the HSV colour space. I want to represent these samples inside the HSV cone to get an idea of how they are distributed. Any thoughts or suggestions on how i could possibly proceed with this? Thanks in anticipation.

See my attempt at doing it in MATLAB attached below in blue.
A better option is to use the Java code that was originally written for ImageJ but can be called from MATLAB. See my code samples in http://www.mathworks.com/matlabcentral/answers/?search_submit=answers&query=color-inspector&term=color-inspector

Just create any image. Like (untested)
k = 1;
for row = 1 : 1000
for col = 1 : 1000
hsvImage(row, col, 1) = hsv(k, 1);
hsvImage(row, col, 2) = hsv(k, 2);
hsvImage(row, col, 3) = hsv(k, 3);
k = k + 1;
end
end
% Now convert that to an RGB image
rgbImage = hsv2rgb(hsvImage);
imwrite(rgbImage, fullFileName);
Then import it into the Color Inspector and view the gamut as HSV.
