Is it possible to define and visualize new metrics (e.g. ratios) in dashboard widgets in Azure DevOp

Hi Paul_Sanders1000​,

Yes, it is now possible to calculate custom metrics (such as ratios, percentages) in ADO by using the widgets offered by Great Gadgets extension available in VS Marketplace: https://marketplace.visualstudio.com/items?itemName=StonikByte.stonikbyte-great-gadgets-extension&ssr=false#overview

This extension offers an Advanced Issue Filter Formula widget that fully covers your second use case "ratio (Count of WorkItems with priority 1 or 2) / Count of all WorkItems".

This is an example:

To obtain this, the widget should be configured like this:

The widget uses the count of multiple shared filters stored in variables a, b, c and then you combine these values in a formula you want (a+b)/c * 100 to obtain the ratio. 

Very useful can be also the Pivot Table & Pivot Chart widget offered by the same extension. 

Hope this helps.
