CHART.VIEW.RANGE
Sets the range of subgroups to be drawn on the chart.
Syntax: CHART.VIEW.RANGE (chart.title, [start.group.no], [end.group.no] )
Reply: Y successful
null unsuccessful
Notes:
- Chart.title is returned by the NEW.CHART command when the chart is created.
- start.group.no and end.group.no are 0-based. If start.group.no is ommited, the
chart will start at the first subgroup. If end.group.no is ommited, the chart
will end at the last subgroup.
- If invalid values are passed for either one of these, the current chart view
will not be changed.
- This command, which implements the "Zoom" and "Pan" features of the program,
does not affect any chart calculations, it only sets which subgroups are visible
on the chart. The subgrouping number reflects the groups that are included in
the chart only. For example, if the chart is based upon the data subgroup
range "1-5,11-15" the chart will have 10 subgroups on it that should be referred
to as 0-9 when calling this function.
- The command is valid for the "scrollable charts" which at this time is types
0, 1, 2, 3, 5, 6, 9, 10, 11, 12, 15, 16, 17, 18.
