Adding Color Fill between Contours
Surfer allows you to fill the areas between contour lines with color fill. The color fill can gradationally change from the minimum to maximum contours, or specific fill properties can be assigned to individual contour levels.
Gradational colors are assigned in the Properties window for predefined color spectrums. Or, gradational colors can be defined in the Colormap Editor. For example, if the color red is assigned to the minimum value, and the color blue to the maximum value, the resulting color spectrum gradually changes from red to blue.
Individual fill colors for specific contour levels can be assigned from the advanced contour levels dialog by double-clicking the fill sample for a contour value on the contour map advanced levels dialog. There is no gradational change for fill patterns.
