// In this example, first we use AutoGrayScale with the default parameters.
// The actual range of the data is from approximately 0 to 10.5. In the
// second example, we color the range of 3 to 11 using the gray scale. By 
// default, outofrange data values get the color of the minimum data value
// or maximum data value, depending on whether they are smaller than min or
// larger than max. In the third example, we explicitly set all outofrange
// data values to the color "red".
