I would like to create a combination chart with three chart types:
1. line chart to show month to month accum total growth for the year.
2. a single bar for each month showing the target.
3. a stacked bar for each month showing two actual total comprise of two
sub-groups.
I can not figure how to combine the bars and obtain one stacked bar and one
single bar. The bars are either all stacked or all single.
