ShadeGeLeContour

Shades contour regions given low and high values and a shade pattern.
(Deprecated. Use gsn_contour_shade.)

Arguments

plot

The plot to be modified.

highval
lowval

Starting with the first contour less than lowval, all areas greater than that first contour and less than the last contour that is less than or equal to highval are shaded with fill pattern pattern.

pattern

The fill pattern to use to shade the given areas.

Return value

plot is returned with the modifications described above.

Description

Starting with the first contour less than lowval, all areas greater than that first contour and less than the last contour that is less than or equal to highval are shaded with fill pattern pattern.

Note that the shading begins at the first contour level less than lowval, and continues until the last contour that is less than or equal to highval. The shading does not begin at lowval, and end at highval. Check your plot to make sure that the results are what you expected.
