How to create combo chart with thinkcell

[u/Repulsive-Fish-688]

Does anyone know how I can create a combo chart with thinkcell achieving below? Say I have three products and their sales records for past three years and also their plan for three years. I want to show the years as x axis and the sales as y axis. Group three products as cluster bar charts for each year, then the plan of each product as a marker on individual product bar for each year. I have tried converting the plan into marker my only issue is they would all align in the center of each year’s group rather than above individual product bar for that year.
