How to show the metrics in percentages in a custom dashboard

[dhanooshd (dhanoosh donepudi)]

Hi team,

We are trying to build a custom dashboard that shows the metrics in percentages. We have created two custom tags. One is the search documentation tag which counts how often the Search Documentation task is qualified. Another one is Nothing Found tag it counts how many times the Search Documentation task displayed the Nothing Found message to the user.

Can we achieve the above functionality using custom dashboards?

Thanks
