Description

In this tutorial you will learn how to use a Toolbar widget to send actions to one or many charts.

Steps

1. Create a dashboard with charts

To complete this step, you can follow the Visualize queries data within charts or you can directly get the example using the following command :

git checkout origin/example-dashboard-charts .

2. Create a Toolbar widget and subscribe to it

Toolbars will send their actions to any chart that subscribed on it. In order to subscribe to a widget, you need to set the widgetSubscriptions property with the id of the toolbar widgets. Charts widgets can be subscribed to multiple toolbars.

In this example, we use a BoxLayout to minimize the height of the toolbar, but it doesn’t affect anything in relation with the communications between the widgets.
