Dynamic charts managed by controls can be downloaded and saved directly from the dashboard anytime. This feature must be specifically enabled for each chart separately and works in the VIEW mode (public view included).
How to enable downloading charts on the dashboard
Select a chart widget;
In the widget menu go to the Chart tab → Chart style;
Tick the checkbox ‘Allow download’.
A 'hamburger' icon appears in the upper right corner of the chart.
Click this icon in VIEW mode and download the chart.
You can download charts in PNG, JPG, and XLSX formats.
