When I enter C-Dash dashboard, there is A-Test widget.
A-Test widget has “Table” and “Pivot Table”.

On C-Dash dashboard, A-Test widget shows default Table.

I want to see Pivot Table of A-Test widget.
How can I change default Visualization type from Table to Pivot Table?

I resolved by myself.
Before adding A-Test widget on C-Dash, you should add “Pivot Table” at A-Test widget.
After that, when you add A-Test widget, you can see “Pivot Table”.
