Chart Type

Combination Chart (Column + Line)​

Chart Function


Use case example: Current and projected annual revenue

The chart in above example presents annual revenue generated by an organization during last 5 years and the projected revenue for next 4 years, with percent growth in year-on-year revenue. 

The columns in this chart template represent dollar values and the line represents percentage increase (auto-calculated) in revenue over previous year. The actual and projected groups are shown along X-axis. 

When you want to present comparison of both the actual revenue earned over last few years and the projected revenue for next few years, you can either use two different chart types or use a chart with grouped X-axis, like in this example. You can further enhance the visual communication by using different color shades for two groups. 


% Change = [ (Revenue in this year - Revenue in previous year) / Revenue in previous year ] x 100
