Combo chart

The combo chart is suitable for comparing two sets of measure values that are usually hard to compare because of the differences in scale. It is basically a bar chart combined with a line chart.

A typical example is when you have a bar chart with sales figures and want to combine these figures with the margin values (in percent). In a regular bar chart, the bars for sales would be displayed as usual, but the margin values would be almost invisible because of the very large difference between the numeric values for sales and margin.

With a combo chart you can combine these values by, for example, using bars for the sales values and a line for the margin values. By default, the bars have the measure axis on the left and the margin values have a separate axis to the right. The two measures use the same dimension (YearMonth).

If you have yet another measure, for example, gross sales, with values that are roughly in the same range as the sales values, you can add the third measure as bars and either stack or group the new measure values with the sales values. With grouped bars, you can easily compare two or more items in the same categorical group. Stacked bars combine bars of different groups on top of each other and the total height of the resulting bar represents the combined result.

The combo chart can only be displayed vertically.

When to use it

With the possibility to have different measure scales, one to the left and one to the right, the combo chart is ideal when you want to present measure values that are normally hard to combine because of the significant difference in value ranges.

But a combo chart can also be quite useful when comparing values of the same value range. In the image above, the combo chart only has one measure axis, but the relationship between the two categories sales and cost is clear.


The combo chart is the best choice when combining several measures of different value ranges.


The combo chart only supports one dimension, and can therefore not be used when you need to include two or more dimensions in the visualization.

Creating a combo chart

You can create a combo chart on the sheet you are editing. In a combo chart, you need at least one dimension and one measure.

  1. From the assets panel, drag an empty combo chart to the sheet.
  2. Click Add dimension and select a dimension or a field.
  3. Click Add measure and select a measure or create a measure from a field. Select to show the measure as a bar.
  4. Add another measure by selecting Add under Height of line. Enter an expression, or master measure item, or a field with an aggregation function applied. By default a line will appear as the measure. You can select More Properties to choose Presentation of the measure as either bars, line, or marker. You can select drop-down options to switch between the Primary axis to the left or the Secondary axis to the right (right and left axes are reversed if Right-to-left is turned on in App Settings). For markers you can choose between several different shapes.

You can only have one dimension, but you can continue adding up to 15 measures. You can only have two measure axes though. This means, if you add three or more measures with a large difference in value range it can be hard to display all measures with a good distribution of values.

When you have created the combo chart, you may want to adjust its appearance and other settings in the properties panel.

Display limitations

Displaying out of range values

In the properties panel, under Appearance, you can set a limit for the measure axis range. Without a limit, the range is automatically set to include the highest positive and lowest negative value, but if you set a limit you may have values that exceed that limit. A bar that exceeds the limit will be cut diagonally to show that it is out of range. For a line data point value that is out of range, an arrow indicates the direction of the value.

Displaying large amounts of data in a combo chart

If the chart uses a continuous scale, a maximum of 2000 data points are displayed. Above that number, data points are neither displayed, nor included in selections made in the chart.

To avoid displaying limited data sets, you can either make a selection or use dimension limits in the properties panel.
