Once you have completed the basic configuration, you can use the buttons at the bottom of the edit view to display a preview of the chart.
On the edit view, to display the preview, click Show Preview. If the current configuration is incomplete, for example if you haven't selected any group dimensions or series metrics, then the button is disabled.
Note that because the preview is a live preview of the actual data, if the query takes a long time to run, it may take a while for the preview to display.
To update the preview to reflect updates to the chart configuration, click Update.
To hide the preview, click Hide Preview.
