Grafana Plugins catalog

No Padding

The removal of the panel padding lets you use the panel space more effectively for displaying charts, maps, and graphics across the entire width and height of the panel.

GeoJSON Map displays requests from users around the world.

Community Use cases

We are amazed by the everyday developments of the community that make use of the latest capabilities in Business Charts Panel for Grafana.

Dynamic toolbox

Our community member ftasso shared an extremely interesting use case that displays complex ECharts objects like a sunburst with the toolbox. It dynamically retrieves data and uses a variety of variables for chart generation.

Preserve the selected range on a visual map

Our community member Barryetter shared another use case that allows you to preserve the range slider settings of the visualMap object after the dashboard refresh.

1. Specify two dashboard variables. Constants are also fine but you need to hide them from the user. Name them datarangeStart and datarangeEnd and apply some initial values to them.
2. In the Apache EChart Panel code editor (before the return snippet), add an event handler for the datarangeselected event. Remove any other event handler to prevent creation of duplicate handlers.

3. In the visualMap definition, set the range property to the dashboard variables using the replaceVariables method as described in our documentation.

Create DOM (Document Object Model) Elements

You can add elements (buttons, checkboxes, dropdown boxes, etc.) to the DOM (Document Object Model) using echartsInstance contributed by Lroy.

Add a button to add Events into the Apache ECharts container.

For example, you can add a button with an event handler.
