Configuration Guide: Across Charts in Looker Studio
A few configurations can be applied to all available charts in Looker Studio (Formerly known as Data Studio), explained with pictures and how to use them.
Background and Border offer ways to customize the appearance of charts individually or on the report level. For instance, you may want to customize your charts to match your company branding color. Consistent and meaningful use of color makes your reports more attractive and easier to understand. You can apply color and border options to every available chart in Looker Studio. If you are unsure about a uniform design, please use the standard design available in Google Data Studio. The color and style settings of these designs are set so that the reports are visually appealing and suitable for color-blind users.
Reference lines show how the data in a chart compares to a reference value or let you show target values and set thresholds and benchmarks. For example, you can use reference lines to visualize daily sales against a target sales figure.
Trend lines reveal the general tendency of the data on a chart. Trend lines allow you to spot patterns and make predictions from otherwise random data. You can add trend lines to time series and scatter charts.
