A combination chart can be made up of area, bar, column, dot, and line charts. Each data series can be represented by a different type of chart. They are all then displayed simultaneously on the same chart. A second axis can be added to the right of the chart to help compare different data series.

Combination charts provide the greatest flexibility when presenting your data in chart format.

An example of a combination chart. It shows a column chart with Actual Units Sold for 2019 until September. There is a line chart laid over this column chart. The line chart displays the Forecast for Units Sold until December.

Combination charts enable you to compare different series of data through different types of chart on the same axes simultaneously. This is useful for visualizing large quantities of data in varied formats.

Adding a chart type that displays over another chart type can give you an immediate comparison of two or more data series over a dimension such as time. For example, In the image above, a line chart displays over a column chart, showing both forecast and actual data on the same chart. Dot and line charts are often displayed over other types of chart as part of a combination chart because they occupy the least visual space, meaning they do not obstruct the view of other data.

You can plot specified data series against an axis with a different scale on the right side of the chart. This enables you to compare data series with large differences in value more easily. If you use a right axis with a different scale, it is good practice to differentiate the corresponding data series by using a different color or chart type for them.

Use a combination chart to answer:

  • How do our actual results compare to our forecast results?
  • Have we, and will we, hit our targets for this financial year?
  • How does A differ from B?
  • Have sales increased over the last financial year?
  • What are the fluctuations in X?

A combination chart may not be the best option when:

  • you don't know what insights you want to highlight; the wide variety of choice when creating combination charts can be overwhelming.
  • you have a basic dataset and want to convey simple insights.

Use a different type of chart if:
