a sort of sneaky way to do it is to set all of the data up with a blank cell
between the machine data indicators.
make a stacked chart of all of the data including the good parts.
select the good part section and change the axis to secodary axis.
then goto <chart<source data<series and change the range for the good
parts up or down one cell to move it on the chart.
This will allow you to have different scales for the good and bad parts.
If you want then to have the same scales another way to do it would be, if
your data is in columns to alternate the good data in one column and all of
the other data in the next column. Then just mnaking a stacked column chart
would do what you want.

I would like to have two columns on the same chart. One will be the amount
of good parts produced by a machine. The other would be a stacked column of
scrap parts produced by the machine. The scrap parts are seperated by
certain defects, but I'd like to see their total compared to the total of
good parts.
