man WMLGND (3): plots weather map legends.

SYNOPSIS

CALL WMLGND (X,Y,NTYPE,IROWS,ICOLS)

C-BINDING SYNOPSIS

#include <ncarg/gks.h>

void c_wmlgnd(float x, float y, int ntype, int irows, int icols)

DESCRIPTION

X

(Real, Input) - An X coordinate (specified in world coordinates) of a point that specifies a position for the legend to be plotted.

Y

(Real, Input) - A Y coordinate (specified in world coordinates) of a point that specifies a position for the legend to be plotted.

NTYPE

(Integer, Input) - A character variable that indicates the desired kind of legend.

Legal values for NTYPE are:

1 - Plot the legend for the weather types. There are six weather types: showers; T-storms; rain; flurries; snow; ice. The coordinate (X,Y) for this type specifies the lower left corner of the legend.

2 - Plot the legend for front types. There are three front types labeled: cold; warm; stationary. The (X,Y) coordinate for this legend specifies the lower right corner of the legend.

3 - Plot the explanatory legend. The (X,Y) coordinate for this legend specifies the bottom center of the legend.

IROWS

(Integer, Input) - An integer variable specifying how many rows there will be in displaying the weather types. IROWS and ICOLS are significant only when NTYPE=1. Choices for IROWS x ICOLS are: 1x6, 2x3, 3x2, and 6x1.

ICOLS

(Integer, Input) - An integer variable specifying how many columns there will be in displaying the weather types. IROWS and ICOLS are significant only when NTYPE=1. Choices for IROWS x ICOLS are: 1x6, 2x3, 3x2, and 6x1.

USAGE

The only internal parameter that controls the appearance of a legend is COL, specifying its color.

ACCESS

To use WMLGND or c_wmlgnd, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
