You may be interested in my color-graduated graph. I posted the URL for an example of this earlier today. Here are the definitons. Notes: This is for one value only. I don't know how you would do more than one value on the same graph using this method. Also, my use of "NoZero" CDEFs is misleading. That should actually be "NoUnknown", since that is what those CDEFs eliminate. A quick-and-easy way of doing the color gradiations is to fire up Photoshop or GIMP, make a gradient, and use the eyedropper tool to sample color values at points along the gradient.
