Unit formats reference

Introduced in GitLab 12.9.

You can select units to format your charts by adding format to your axis configuration.

Internationalization and localization

Currently, your internationalization and localization options for number formatting are dependent on the system you are using i.e. your OS or browser.

Engineering Notation

For generic or default data, numbers are formatted according to the current locale in engineering notation.

While an engineering notation exists for the web, GitLab uses a version based off the scientific notation. GitLab formatting acts in accordance with SI prefixes. For example, using GitLab notation, 1500.00 becomes 1.5k instead of 1.5E3. Keep this distinction in mind when using the engineering notation for your metrics.

Formats: engineering

Numbers

For number data, numbers are formatted according to the current locale.

Formats: number

Examples:

Data Displayed
10 1
1000 1,000
1000000 1,000,000

Percentage

For percentage data, format numbers in the chart with a % symbol.

Formats supported: percent, percentHundred

Examples:

Format Data Displayed
percent 0.5 50%
percent 1 100%
percent 2 200%
percentHundred 50 50%
percentHundred 100 100%
percentHundred 200 200%

Duration

For time durations, format numbers in the chart with a time unit symbol.

Formats supported: milliseconds, seconds
