Combo chart

How to use and configure combo charts.

A combo chart lets you use either lines, bars, or both to visualize your data. Combo charts can plot both time-based and non-time-based data on the X-axis.

Combo charts in Data Studio

Combo charts can plot a single dimension with up to 5 metrics, or 2 dimensions with a single metric.

Combo chart example

You are launching a series of mobile apps and want to visualize the download and 7-day active metrics for the different product versions. Your data might look something like this:

Product Days Since Launch Downloads 7-Day Active
MyApp 2.0 1 1000 0
MyApp 2.0 2 1330 0
MyApp 2.0 3 1800 0
MyApp 2.0 4 3600 0
MyApp 2.0 5 3501 0
MyApp 2.0 6 3700 898
MyApp 2.0 7 3333 1194
MyApp 2.1 8 3000 1381
MyApp 2.1 9 3200 1515


Here's a data source based on this data:

data source example.


The following combo charts show 2 ways you could visualize this data. Both charts use Days Since Launch as the primary X-axis dimension. The chart on the left shows the Downloads metric broken down by the Product dimension. The chart on the right shows both the Downloads and 7-Day Active metrics. The chart variation on the right could actually plot up to 5 metrics.

Combo chart examples


Set the default sort

The Sort and Secondary sort options in the chart's DATA properties panel control the default sorting behavior. You can select any metric in the chart's data source, or any dimension currently displayed in the chart, to use as the primary or secondary sorting field.

The Secondary sort option only appears when there is an appropriate combination of dimensions and metrics in the chart.
When specifying a metric as a sort field, you can edit the field's aggregation. For example, you could include a numeric field in the chart as a SUM, but sort on that same field's AVERAGE value.

Section Property Notes

Dimensions provide the data series for your chart.

 At least 1 dimension is required. The first dimension you specify serves as the primary data series in the chart. If you specify a second dimension, this serves as a breakdown dimension for the first dimension. Note that if you specify a second dimension, the chart is limited to a single metric.

Metrics provide the numeric scale and data series for the chart.

 At least 1 metric is required. For charts with a single dimension, you can have up to 5 metrics. For charts with 2 dimensions, you can have 1 metric.

Sets the primary sorting options for the chart. When the chart has a single dimension, you can sort by the dimension, or any of the metrics.

Secondary Sort

Secondary sort lets you set an extra level of sorting, based either on the breakdown dimension or the selected metric.

Default Date Range

The default date range property lets you set a timeframe for an individual chart. Learn more about working with dates and time.

  Auto Use the default date range determined by the chart's data source.
Custom Lets you use the calendar widget to select a custom date range for the chart.

The filter property restricts the data displayed in the component by including or excluding the values you specify. Learn more about the filter property.

  Filter name Click an existing filter to edit it. Mouse over the filter name and click X to delete it.
+Add a filter Creates a new filter for the chart.


Combo chart STYLE tab properties

Section Property Notes
Color By

This section controls how your data is colored. Learn more about coloring your data.

These options appear when you have a secondary (breakdown) dimension in your chart.
  Series order Use the current theme to color the data according to its position in the chart. This option emphasizes the ranking of the data over the identity of the data.
Dimension value

Colors each dimension value in the chart with the color specified in the dimension value color map. This option ensures that your data uses color consistently, regardless of the position of that data in the chart.

Series #n

This section repeats for each metric displayed in the chart. The order of sections matches the order of the metrics listed in the DATA tab.

  Line or Bars Displays the data points for this series as a line or bar.
Line weight Determines the thickness of line series.
Series color Sets the color for the series line or bar.
Cumulative When checked, data for this series is summed over time. Otherwise, the data is shown with no additional aggregation.
Show points Displays individual data points on a line series. Viewers can mouse over a data point to display its value.
Show data labels Displays individual values on for the data points in the series.
  Number of points Determines the number of data elements shown in the chart's X-axis. If the number of points selected is less than the number of values in the X-axis dimension, only the top N points will be shown (where N equals the number of points you've selected).
Number of series Determines the number of secondary dimension series shown in the chart. If the number of series selected is less than the number of series in your data, only the top N series will be shown (where N equals the number of series you've selected). Remaining series will be grouped in an "other" category.

These options determine the placement of the chart legend.

  None No legend appears
Right Legend appears on the right.
Bottom Legend appears on the bottom.
Top Legend appears on the top.
Alignment Sets the alignment of the legend relative to the selected position. 
Max lines Sets the number of lines used by the legend. If the number of series requires more lines, overflow items can be displayed by clicking the < and > arrows.

These options control the display of the chart axes titles and scales. A right Y-axis section appears when you have more than 1 metric in your chart.

Show axes Shows or hides the chart axes.
Reverse Y-Axis direction Controls the vertical display of the Y-axis.
Reverse X-Axis direction Controls the horizontal display of the X-axis.
Show axis title Shows or hides the axis labels. 
Axis min and max Set minimum and maximum values for the Y-axes.
Custom tick interval Controls the interval between axis ticks.
Log scale Makes the Y-axis scale logarithmic.l


These options control the look of the chart grid.

  Axis color Sets the color of the x-axis line.
Grid color Sets the color of the grid lines.
Chart background Sets the color of the chart background.
Chart border color Sets the color of the inner chart border.
Background and Border

These options control the appearance of the chart background container. 

  Background Sets the chart background color.
Border Radius Adds rounded borders to the chart background. When the radius is 0, the background shape has 90° corners. Border radius of 100° produces a circular shape.
Opacity Sets the chart's opacity. 100% opacity completely hides objects behind the chart. 0% opacity makes the chart invisible.
Border Color Sets the chart border color.
Border Weight Sets the chart border line thickness.
Border Style Sets the chart border line style.
Add border shadow Adds a shadow to the chart lower and right borders.
