.XY SET BAR OLAP:ORDER

This subroutine sets the order among overlapping bars within a bar group in a multi-bar chart.

Usage:

      PASS         <olap_order>               FIELD            SHARE? N
      GOSUB    0CD .XY SET BAR OLAP:ORDER
      *        Check for error
      IF       0CD .XY SET BAR OLAP:ORDER     NE

Description:

This subroutine sets the order among overlapping among bars within a bar group in a multi-bar chart.

You have to define a Layer via .XY ADD BAR LAYER for this subroutine to have any effect.

The parameter is optional, and if blank or not passed, will be reset to the default value.

<olap_order> - Valid values are First, Firstontop, First On Top, Last, Lastontop, Last On Top. If this value is First, Firstontop, or First On Top, the first data set will be on top of the second data during overlapping, and the second data set will be on top of the third data set, and so on. If this value is Last, Lastontop, or Last On Top, then the overlapping order will be reversed.

Also see .XY SET BAR OLAP to the order and ratio at the same time or .XY SET BAR OLAP:RATIO to set the ratio by itself.
