.XY SET PA HGRID CLR

This subroutine sets the horizontal grid color of the "current" chart spec.

Usage:

      PASS         <color_spec_name>          FIELD            SHARE? N
      *        OR
      PASS         <color_value>              FIELD            SHARE? N
      GOSUB    0CD .XY SET PA HGRID CLR
      *        Check for error
      IF       0CD .XY SET PA HGRID CLR       NE

Description:

This subroutine set the horizontal grid color of the chart area for the "current" chart spec. You must have initialized the chart as an XY Chart via .CHART INITIALIZE for this to have any effect. This routine receives one, optional value specifying either a <color_spec_name> or a <color_value>.

If the parameter is not received or if the value received is blank, then the horizontal grid color of the chart spec is cleared and the default horizontal grid color will be rendered (#C0C0C0).

If a parameter is received, the system first assumes that the value received is a <color_spec_name> and checks to see if a color spec record has been previously initialized with that name. If a color spec record is found, then that color spec record is used as a prototype to create a color spec for the horizontal grid color. If a color spec record is not found, then the system assumes that the value received is a literal <color_value> and uses the specified color to create a color spec for the horizontal grid color.

After setting the horizontal grid color, the horizontal grid color spec becomes the "current" color spec.

See ColorSpec for more information on working with colors.
