Grafana Custom Legend: Enhancing Visualization and Dashboard Customization

Grafana Custom Legend


Grafana is a popular open-source platform for visualizing time series data. It provides a wide range of features and customization options to create interactive and informative dashboards. One such customization feature is the ability to create a custom legend.

What is a Legend?

In data visualization, a legend is a key that provides information about the data series or elements displayed on a chart or graph. It helps users understand the meaning and representation of different colors, shapes, or patterns used in the visualization.

Why Customize the Legend?

While Grafana provides a default legend that automatically displays the series names and colors, there are cases where customizing the legend becomes necessary. Some reasons to customize the legend include:

1. Improved readability: Customizing the legend can make it easier for users to understand the data series and their corresponding values.

2. Highlighting important information: By customizing the legend, you can draw attention to specific data series or elements that are more relevant or critical.

3. Branding and aesthetics: Customizing the legend allows you to align it with your organization’s branding guidelines or enhance the overall visual appeal of the dashboard.

1. Open the Grafana dashboard editor and navigate to the panel where you want to customize the legend.

2. In the panel settings, locate the «Legend» section and click on it.
