ShadeLtGtContour

Shades contour regions below a given value and above a given value with the specified fill patterns.
(Deprecated. Use gsn_contour_shade.)

Arguments

The plot to be modified.

Starting with the first contour less than ltvalue, all areas less than that first contour will be shaded with fill pattern ltpattern.

The fill pattern to use to shade the given areas specified by ltvalue.

Starting with the first contour less then gtvalue, all areas greater than that first contour will be shaded with fill pattern gtpattern.

The fill pattern to shade the given areas specified by gtvalue.

Return value

plot is returned with the modifications described above.

Description

Starting with the first contour less than ltvalue, all areas less than that first contour will be shaded with fill pattern ltpattern. Starting with the first contour less than gtvalue, all areas greater than that first contour will be shaded with fill pattern gtpattern.

Note: The shading begins at the first contour level less than gtvalue, and not at the specified gtvalue. The shading also begins at the first contour level less than ltvalue, and not at the specified ltvalue. Check your plot to make sure that the results are what you expected.
