Hi SB1962,
Thanks for visiting Microsoft Community.
After my testing, it seems there is no direct way to combine a clustered column chart with a stacked column chart.
If a secondary axis is set for the data of Series 1 and Series 3 in a clustered column chart, a similar effect can be achieved. However, there is no way to directly plot Series 2 on top of the data of Series 1 (Excel will require it to be plotted either on the primary horizontal axis or on the secondary horizontal axis).
If you want to achieve the same graphical effect as a stacked column chart, you need to process the data so that the data of Series 2 is first added to the corresponding data of Series 1 on its own basis, and then plotting can achieve the effect.
I hope this information can help you confirm the situation.
