GPROBCNT Call

draws probability contours

RUN GPROBCNT( x, y<,p>) ;

The inputs to the GPROBCNT subroutine are as follows:

is any matrix of values.

is a corresponding matrix of values.

is an optional probability value matrix.

The GPROBCNT module draws one contour curve for each value in the matrix , which must contain entries between zero and one. If you do not specify the matrix , contours for the probability values of 0.5, 0.8, and 0.9 are drawn. You cannot produce graphics until you specify the CALL GSTART statement. The contour plot remains open for further additions until you specify the CALL GCLOSE statement, which terminates the current graphics segment. Note that this module cannot be used for general contour plots of three-dimensional data.
