Donut Multiples chart options

To select a donut multiples chart, click the ellipses (…) on the Visualization menu bar and select Donut Multiples.

This page describes the options for editing donut multiples charts in the visualization menu. This menu can be accessed by clicking the gear in the upper right corner of the visualization tab.

Please note that some of the options listed below may be grayed out or hidden in situations where they would conflict with other settings you have chosen.

Plot menu options

Value Labels

Value Labels toggles the appearance of value labels for each data point on a chart.

Series Label Size

Series Label Size changes the font size of the labels that appear in the middle of each donut multiple.

Number of Charts per Row

Number of Charts per Row defines the maximum number of donuts that will appear in a single row of the donut multiple chart. If this parameter is not set, the default value is 3.

Hide Legend

Hide Legend toggles the appearance of the series legend on a chart. This is only available when there is more than one series (except in the case of a pie chart).

Series menu options

The series menu controls how your chart shows each data series.

Colors

You can define the color palette for a chart in the Colors section.

Collection

Choose a color collection from the Collection drop-down menu. A collection allows you to create themed visualizations and dashboards that look good together. You can see all the palettes in each of Looker's built-in color collections on the Color collections documentation page. Your Looker admin may also create a custom color collection for your organization.

Once you select the color collection, the Palette section will update with a palette from that collection.

Palette

Once you've selected a color collection, you can choose a different palette from the collection, or customize your palette, by clicking the color palette itself. This opens the palette picker and displays all the palettes from the collection.

Colors are assigned to each series in order. For a categorical palette, the first color in the palette is assigned to the first series, and so on. For a sequential or diverging palette, the color at the left end of the palette is assigned to the first series and the colors for each remaining series move to the right on the palette. If your query returns more data series than colors listed, the colors repeat from the beginning of the palette, first as a lighter version of each color, then as a darker version of each color.

Creating a custom color palette

To create a custom color palette, first select the Custom tab on the palette picker. You can edit your palette in several ways:

  1. Click on one of the colors present to edit it.
  2. Click the + or - buttons below the color palette to add a color to the end of the palette or remove a selected color.
  3. Click EDIT ALL at the bottom right of the menu to use a comma-separated list of color values.

To change a selected color, or edit all colors at once, you can input hex strings, such as #2ca6cd, or CSS color names, such as mediumblue, into the color value box at the bottom of the picker.

You can also click the color wheel to the right of the color value box to bring up a color picker, which can be used to select a color. The corresponding hex value for that color appears in the color value box:

If you click EDIT ALL, you'll see that the color value box is populated with the hex codes of the color palette you've chosen or customized. Copying and pasting this list is the best way to copy custom color palettes from one chart to another.

Reverse colors

Select Reverse colors to reverse the palette. For a categorical palette, this would apply the last color in the palette to the first series, the second-to-last color in the palette to the second series, and so on. For a sequential or diverging palette, this would apply the color at the right end of the palette to the first series and move left on the palette for the remaining series.

Customizations

Each series in the chart can be customized in several different ways:

  1. Click the arrow next to a series to expand its options.
  2. Click on the color swatch to select a custom color for the series. This overrides the color palette defined by the Colors option.
  3. Enter a custom series label if desired. This impacts the chart legend and tooltips.
