Area Chart

Area charts allow you to present data for a particular period, but they also allow you to segment the data by choosing a breakdown dimension. For example, when using Google Analytics data, the area chart will show you traffic by day broken down by traffic source.

Chart – Area charts allow you to present data for a particular perio

Arrange

Choose how charts and elements are arranged in the report. You can place elements so they are in front or behind other items. Here are some keyboard shortcuts you can use to speed things up (replace ⌘ with CTRL if you’re using Windows):

  • Bring to front ⌘+Shift+↑
  • Bring forward ⌘+↑
  • Send backward ⌘+↓
  • Send to back ⌘+Shift+↓

You can also select multiple elements to align them horizontally, vertically, or distribute them. See also make report-level and group.

Bar Chart

Bar charts allow you to categorize and rank data. For example, a bar chart can be used to compare product sales, marketing channels and more.

Chart – Bar charts allow you to categorize and rank data. For exampl

Bins

Bins let you present values as ranges. For example, instead of reporting the exact number of active users for each landing page, you can group them into ranges like 0 to 1000, 1000 to 2000, and so on. This is especially useful when you want to show patterns in your Google Analytics data, like grouping users based on the number of key events they triggered.

Bullet Chart

A bullet chart allows you to add a single metric to your report. Bullet charts can be useful for presenting KPIs because you can set a target for the metric.

Chart – A bullet chart allows you to add a single metric to your rep

Blended Data

Combine data from multiple data sources into a single chart by creating 'blended data'. To combine data, you will need to add at least two data sources to your report and then choose a common dimension (a 'join key') from both data sources.

Cache

See data freshness.

Calculated Field

Calculated fields (or custom fields) allow you to create new metrics and dimensions based on existing metrics and dimensions available from your data source.

Calculated Field Formula

You can input different types of formulas to create calculated fields. You can use basic math formulas:

  • Addition: +
  • Subtraction: -
  • Division: /
  • Multiplication: *

And you can use functions:

  • Aggregation, including SUM() and COUNT()
  • Arithmetic, including ROUND()
  • Date, including DAY(), WEEK() and YEAR()
  • Geographic, including TOCITY() and TOCOUNTRY()
  • Text, including LOWER() and REGEXP_REPLACE()

You can also use CASE statements to modify values. For example, if you wanted to clean up campaign names in your report you could use a formula like:

CASE
    WHEN REGEXP_MATCH(Session Campaign, ".*(AW - Dynamic
    Search Ads Whole Site|AW - Accessories)") THEN "Ads"
    WHEN REGEXP_MATCH(Session Campaign, "(Data Share
    Promo|Special Promo)") THEN "Promotion"
    ELSE "Other"
END

Canvas Size

You can change the size of the pages in a report by adjusting the canvas size. You can select from US letter (portrait and landscape), screen (portrait and landscape) and custom.

Combo Chart

A combination chart allows you to combine a bar chart with a time series. See also bar chart and time series.

Chart – A combination chart allows you to combine a bar chart with a

Community Connectors

Apart from the built-in data connectors, you can also make use of third-party connectors. These can make it easier to pull data from other platforms into Looker Studio. For example, Supermetrics (affiliate link) provides a range of community connectors, allowing you to connect Bing Ads, Facebook Ads, Facebook Insights, Instagram and more. These third-party connectors generally require a paid subscription. See also connector.

Community Visualizations

Community visualizations are custom-built charts created by third-parties. They extend the types of visualizations you can use in your reports. For example, you can add radar charts, sunburst charts, or funnel visualizations not included by default.

Compact Numbers

When data is presented in a chart, like a table, you can choose to display the full metric (number) or a short number. For example, a metric with the value of 10,398 would be shown at 10K as a compact number. To use a compact number select the ‘Style’ tab on the properties panel after you’ve selected a chart.

Connector

A connector allows you to link a data source to your report. For example, the Google Analytics connector allows you to select a reporting view and data from that view is then made available in your report. You can use multiple data connectors with a report to bring data from different platforms together in a single report. 

Connectors include:

  • Google Analytics
  • Google Ads
  • Google Sheets
  • BigQuery
  • File upload
  • MySQL
  • Search Console
  • YouTube Analytics
  • Etc.

Control

You can add a control to your report to make it more dynamic. For example, adding an 'Input Box' control lets people search for values in a report. Control options include drop-down lists, fixed lists, inputs, advanced filters, sliders, and checkboxes. See also date range control and data control.

Credentials

When you add a data source, it will automatically make the data available to anybody who has access to the report. This is the default option which is ‘Owner’s Credentials’. You can also require that anyone who has access to the report also needs access to the underlying dataset. To do this, you’ll need to select ‘Viewer’s Credentials’ for the data source.

Cross-filtering

Cross-filtering lets viewers interact with your charts to filter the rest of the report. For example, clicking on a bar in a bar chart can filter a table below it. This makes it easier for viewers to explore the data and see trends without needing to use controls like drop-downs or sliders.

Current Page Settings

The current page settings allow you to select a data source for all of the charts on the current page. You can then select a default date range and filter for all the charts. The current page settings are available under the ‘Page’ drop-down.

Data Control

You can add a data control to quickly change the data used for the charts when viewing the report. For example, adding a Google Analytics data control allows you to quickly switch between the reporting views you have access to, to update the tables in the report.

Data controls are currently available for:

  • Google Analytics
  • YouTube Analytics
  • Google Ads
  • Campaign Manager
  • Search Console
  • Google Ad Manager 360

You can also select one or more charts and group them with the data control. Only the grouped charts are updated with the selected data source.

Data Freshness

Controls how often Looker Studio fetches new data from your data source. For example, a freshness setting of 12 hours means the data is updated twice a day. This helps improve performance by reducing how often queries are run. You can adjust freshness settings for each data source.

Data Source

Once a platform is connected to Looker Studio, it becomes a data source for the report. A data source includes all of the dimensions and metrics from the selected platform, as well as any calculated fields that have been created. See also connector.

The data source also allows you to modify how metrics and dimensions are treated in the report. For example, you can change a metric from a number to a percent, and decide if the data should be aggregated or not.

Data Source Access

See credentials.

Date Range

Each chart has a date range which determines the amount of data that it presents. The default date range can be changed to a custom date range. Custom date ranges can be fixed (and not change) or dynamic which will mean the data will be different depending on when you view the report. Dynamic date range options include:

  • Last 7 days
  • Last 14 days
  • Last 28 days
  • Last 30 days
  • Today
  • Yesterday
  • This week
  • Last week
  • This month
  • Last month
  • This quarter
  • Last quarter
  • This year
  • Last year
  • Advanced

Default Date Range

The default date range for charts is the last 28 days worth of data, excluding today.

Dimension

A dimension is typically information, like an attribute or characteristic. For example, if you connected data from Google Ads, then common dimensions include the name of your campaigns and your keywords. See also metric and dimension in the Google Analytics Glossary.

Time Dimension

The time series chart allows you to select a time dimension. This allows you to control how your data is graphed. By default, each point on the chart will be for an individual day (by date), but you can choose from other time dimensions including; hour, day of week, month of year and so on. Other charts, for example, bar charts, also allow you to select a dimension based on time to present data.

Breakdown Dimension

The breakdown dimension allows you to apply a second dimension to a chart to see more detail. For example, with a Google Analytics data source, an area chart can use ‘date’ as the dimension and ‘medium’ as the breakdown dimension. This visualizes the top ways people are finding your website for each day in the chart.

Dimension Value Colors

Dimension value colors allow you to choose the color used for a unique value across all of the charts in your report. For example, if you have multiple charts that compare paid and organic traffic, then the dimension value color means that ‘organic search’ and ‘paid search’ will always be presented using the same colors, even if they are in different charts. You can adjust the colors for each dimension value in your report.

Drill Action

Drill Actions let people explore deeper layers of data in your charts. You can add 'Drill Down' or a 'Drill Through' to an individual dimension in a chart.

Adding a 'Drill Down' lets people click a dimension (like 'Country') to reveal a more detailed level (like 'City' or 'Region'). While adding a 'Drill Through' lets you add external URLs to dimensions so people can access additional information or resources.

Drill Down

Adding a drill down to a chart lets you layer dimensions so people can click to see more detail. For example, a chart might start by showing users by country, and then when a country is clicked, it drills down to show cities.

Embed Report

You can embed a report on your website by enabling the embedding option. This works in combination with the sharing and data source access setting for the report. If you want an embedded report to be viewed by anybody, you’ll need to set sharing to ‘Public’.

Explorer

The 'Explorer' tool lets you present data in a single chart. It's designed to streamline data exploration by quickly presenting data. You can apply filters and change charts, but sharing and other features are limited. Explorer reports are not automatically saved.

Export Data

When viewing a report you can export the underlying data used for a chart. To do this hover over the chart, select the three vertical dots on the top right corner and then select one of the export options.

Field

A field is a dimension or a metric which is used in your report. After you’ve added a data source all of the fields will be available to use in your charts. Looker Studio highlights dimensions in green and metrics in blue. See also dimension and metric.

Field Aggregation

Field aggregation allows you to control how metrics are treated. For built-in data connectors, like Google Analytics, Google Ads and Search Console, you can leave the aggregation on ‘Auto’. For other data sources and calculated fields you can choose from the following options:

  • None
  • Average
  • Count
  • Count distinct
  • Maximum
  • Minimum
  • Sum

Field Type

The field type controls how the dimension or metric is treated in your reports. For example, if you add Google Analytics as a data source, then the ‘users’ metric will have a ‘number’ as the field type. This is because the users metric should show the total number of users in our report. Compared to bounce rate which will have ‘percent’ as the field type. When you connect third-party data sources, it’s important to check the field type to ensure the dimension or metric is presented correctly in your charts. Field types include:

  • Numeric
  • Text
  • Date and time
  • Boolean
  • Geographic
  • Currency
  • URL

Field Editing

Field editing allows you to customize fields directly in a chart without changing the entire data source. You can change how a metric is calculated, modify a formula, or adjust the format. Changes are only applied to the individual chart.

Filter

Filters can be applied to a chart to modify the data that it uses. Filters allow you to include or exclude particular pieces of data using conditions. You can use ‘or’ and ‘and’ statements within a filter to further refine the data that is included in the chart. Once a filter has been created it can be applied to multiple charts in the report.

Filter Control

Adding a filter control allows people viewing the report to control the data that is included. Filter controls will update all of the charts on a page unless the filter control has been grouped with a chart (or charts), in which case, only the charts in the group will be changed.

Full-screen

You can view a report in full-screen mode by selecting the full-screen icon at the top of the window.

Geo Chart

The geo chart allows you to present data using a geographic map. See also zoom area.

Chart – The geo map chart allows you to present data using a geograp

Google Maps

This visualization option presents data on a Google Map. Google Map chart options include:

  • Bubble map
  • Filled map
  • Heatmap
  • Line map
  • Connection map
  • Combo map

Group

You can group charts, date range, filter control and data control elements in your report. When you group elements you can select a data source, default date range and filter for all the selected charts.

Group Data

A group lets you combine multiple values from a field into categories. This is helpful when you want to simplify your data. For example, grouping different product types or traffic sources together for a cleaner report. You can create custom groups inside your charts by selecting 'Add Dimension' and then choosing 'Add Group'.

Header Visibility

When viewing a report, you will see the name of the report, pagination and other options at the top of the window. The default option for header visibility is ‘always show’, but you can also select ‘auto hide’ and ‘initially hidden’. See also view mode.

Heatmap

The table and pivot table chart types allow you to apply a heatmap to the data that’s presented. For example, this can be used to highlight pages that have a higher bounce rate.

Chart – Thetableandpivot tablechart types allow you to apply a heatm

Image

You can add images, like logos to your Looker Studio reports.

Keyboard Shortcuts

Here are some handy keyboard shortcuts you can use with Looker Studio (replace ⌘ with CTRL if you’re using Windows):

  • Duplicate: ⌘+D
  • Undo: ⌘+Z
  • Redo: ⌘+Y
  • Select All: ⌘+A
  • Select None: ⌘+Shift+A
  • Group: ⌘+G

Layout

Your layout controls the appearance of your report and charts. When you create a new report you will be prompted to select from 'Freeform Layout' or 'Responsive Layout'.

  • Freeform Layout gives you full control with fixed size report pages and fixed size charts.
  • Responsive Layout automatically adjusts your report and charts for different screen sizes.

Log Scale

Selecting the log scale option will mean that the x-axis in a chart does not equally space the values. For example, instead of the intervals being at 0, 5K, 10K, 15K and 20K, they could be presented at 1, 10, 100, 1K, 10K and 100K. In most cases, you should avoid using log scale as it makes it difficult to interpret the data.

Looker Studio Pro

Looker Studio Pro is the paid version of Looker Studio. It includes extra features designed for teams and enterprise users, like team workspaces, expanded admin controls, SLAs, and audit logs.

Make Report-level

You can select elements on a page, select ‘Arrange’ and then ‘Make report-level’. This means that the selected elements will be placed on every page in the report. This is useful if you want to include consistent branding or other elements on every page, like a filter control or data control.

Make Page-level

If an element has been applied to all of the pages in the report with the make report-level option, you can remove this by selecting the element, then ‘Arrange’ and ‘Make page-level’. This will mean the element is now only applied to the current page.

Metric

A metric is typically a number, like a numerical count or a percentage. For example, metrics include the number of users from Google Analytics and the number of ad clicks from Google Ads. See also dimension and metric in the Google Analytics Glossary.

Metric Sliders

Enabling the 'Metric Sliders' option lets you adjust the range for metrics included in a chart. For example, if a table contains rows with values from 100 to 10,000, you can use the slider when viewing the report to only show rows with values from 1,000 to 2,000 (or any other available range).

You can change the position of pagination using navigation position. The default position is ‘top’, enabling you to navigate between pages on the top left corner of the report. This can be changed to ‘left’ which shows all the pages of the report to the left of the report canvas.

Page

You can add additional pages to the report and copy existing pages. Select the current page when editing the report and then click ‘Add a new page’ or select the three vertical dots for an existing page and then select ‘Duplicate’.

Parameters

Parameters let you add inputs to a report that dynamically change calculations or filters. For example, you could create a parameter to let someone enter a custom revenue target or select a region to update multiple charts at once. Parameters can be paired with calculated fields to create flexible, interactive reports.

Pie Chart

Pie charts allow you to structure data so you can see the percentage breakdown.

Range Limits

Bullet charts include range limits which allow you to set the range for the minimum, middle and maximum range values. You can think of range limits as a way to set the lower, middle and upper targets for a metric. See also bullet chart.

Refresh Data

You can refresh the data in a report by clicking the refresh icon at the top of the window. This will fetch current data (based on the date range of the charts) from the data sources.

Report Settings

Report settings allow you to set a default data source, default date range, filter, cache and other options for all the charts in the report. You can also track how people use your report by adding a Google Analytics tracking ID. You can access the report settings by selecting ‘File’ and then ‘Report settings’. 

Report-level Component Position

You can choose if elements that have been added to all pages with the make report-level option are placed above (by selecting ‘Top’) or below (by selecting ‘Bottom’) all other elements on pages. To set the report-level component position click on the canvas (and deselect any charts). The setting is available at the bottom of the ‘Layout’ tab.
