.LEGEND SET KEY GAP:V

This subroutine sets the vertical gap between two legend entries for "current" Legend Box.

Usage:

      PASS         <vert_gap>       FIELD            SHARE? N
      GOSUB    0CD .LEGEND SET KEY GAP:V
      *        Check for error
      IF       0CD .LEGEND SET KEY GAP:V     NE

Description:

In vertical legend layout, the legend entries will flow from top to bottom, with one entry per line. This subroutine allows you to set the line spacing in pixels.

The parameter is optional, and if supplied must be an unsigned integer in the range 0-999. If not received or blank, the gap will be automatically determined.

This can also be set along with horizontal spacing via .LEGEND SET KEY GAP or you can set the horizontal spacing directly via .LEGEND SET KEY GAP:H

You have to define a Legend box via .CHART SET LEGEND BOX for this subroutine to have any effect.
