You can export any report on a dashboard as an SVG, PNG, or JPEG.
To export a report, click on the Export button in the upper right corner of the VisualScript gadget.
Export is available both if you're the creator of the dashboard and if you're just a viewer of it.
If you're the creator of the dashboard, you'll also see the option to "Change Report" and "Edit Parameters". If you don't have edit rights on the dashboard, you'll only see "Export."
