Combo chart
A combo chart is a combination of more than one chart type, and it is usually one of the following combinations:
- Line and column charts combination
- Line and bar charts combination
- Area and column charts combination
- Area and bar charts combination
- Any combination of line, bar, column, and area charts
Combo charts are useful for showing multiple insights without needing to plot two separate charts. You could combine a column chart of monthly sales with a line chart of profit margin. This ensures the user focuses on the whole message intended.
