WMLGND(3NCARG)

NAME
WMLGND - 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.
