How to use and configure bar charts.

A bar chart uses horizontal or vertical bars to show comparisons among categories. The longer the bar, the greater the value it represents. One axis of the chart shows the specific categories (dimensions) being compared, and the other axis represents a discrete value (metric).

Bar charts in Data Studio

You can use a bar chart in Data Studio to look at your data in 2 distinct ways, depending on the number of dimensions in the chart. When your chart includes a single dimension, the data series come from your metrics. You can show up to 5 metrics in a single dimensional bar chart.

When a bar charts includes 2 dimensions, the data series come from the second dimension. Two dimensional charts can show any number of data series but only 1 metric.

Either kind of chart can be displayed as a grouped graph, which makes it easy to compare values within a series, or as a stacked graph, which is better at showing the cumulative effect of the series values.

Bar chart example

The bar charts below show 2 different views of Google Analytics web traffic data. The base dimension for both charts is Medium. The left hand chart uses stacked bars to show several metrics (Sessions, Users, and Exits) for medium. The right hand chart uses a second dimension, Country ISO Code, to breakdown each medium according to its country of origin. Instead of stacked bars, this chart use grouped bars: each bar is a data series corresponding to one of the countries. Two dimensional charts can only plot a single metric (Sessions again in this example).

Bar chart examples

Configure the chart

Select the chart, then on the right, use the properties panel to configure the chart options.

Data properties

The options in a chart's data properties panel affect how the data is organized and displayed.

Data source

A data source provides the connection between the component and the underlying data set. Data source options are:

  • To change the chart's data source, click the current data source name.
  • To view or edit the data source, click Edit. (You must have at least view permission to see this icon.)
  • Click +BLEND DATA to see data from multiple data sources in the same chart. Learn more about data blending.

Dimension 

Dimensions are data categories. Dimension values (the data contained by the dimension) are names, descriptions or other characteristics of a category.

Add dimensions to the chart by dragging fields from the Available Fields panel on the right. You can also click Add dimension in the Data tab.

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

Drill down

This option appears on charts that support drill down.

Drilling down gives viewers a way to reveal additional levels of detail within a chart. When you turn on Drill down, each dimension you add becomes another level of detail you can drill into. Learn more about chart drill down.

Breakdown dimension

The Breakdown Dimension displays the metric data broken down according to the selected dimension. For example, a chart showing annual sales data could be broken down by a Sales Region dimension to show sales by region, or by an Employee ID dimension to show sales by sales associate.

Date range dimension

This option appears if your data source has a valid date dimension. For Ads and Analytics data sources, this option is automatically set to the Date dimension.

The Date Range Dimension is used as the basis for limiting the date range of the chart. For example, this is the dimension used if you set a date range property for the chart, or if a viewer of the report uses a date range control to limit the time frame.

Metric

Metrics measure the things contained in dimensions and provide the numeric scale and data series for the chart.

Add metrics to the chart by dragging fields from the Available Fields panel on the right. You can also click Add metric in the Data tab.

At least 1 metric is required. For charts with a single dimension, you can have up to 20 metrics. For charts with 2 dimensions, you can have 1 metric.

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.

Default date range

The default date range property lets you set a timeframe for an individual chart.

Default date range options

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.
Date compare type Displays comparison data for the selected time period.

Learn more about working with dates and time. 

Google Analytics segment

This option appears for charts based on a Google Analytics data source.

A segment is a subset of your Analytics data. You can apply segments to your Data Studio charts to help ensure that your Data Studio and Google Analytics reports show the same data. Learn more about Analytics segments in Data Studio.

Filter

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 options

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.

Interactions

When interactions are enabled on a chart, that charts acts like a filter controls. You can filter the report by clicking or "brushing" your mouse across the chart. Learn more about chart interaction filters.

Style properties

A chart's style properties control the overall presentation and appearance of the chart.

Bar Chart

This section controls the overall appearance and layout of your chart.

Vertical Displays the data series as vertical bars.
Horizontal Displays the data series as horizontal bars.
Bars Determines the number of data 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).
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).
Stacked Bars When checked, the chart displays stacked bars. Otherwise, the chart displays grouped bars.
100% Stacking When checked, stacked charts show the contribution of each data series to 100% of the total value.
Show Data Labels When checked, displays the value for each series in chart.

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.

Single Color
When checked, the data series are displayed in shades of a single color. Otherwise, the chart displays in a veritable rainbow of happy colors (depending on your report theme).

You can change the series colors using the color pickers below.

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.

You can set specific colors using each data series' color picker.

Dimension values

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.

Axes

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.

Axis options

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

Grid

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.
