How to delete custom metrics Application insights?

How can I delete custom metrics I've created from Azure Portal Application Insights? Is it any query you can make to delete all the data?

I've created the metrics from C# code.

You can use this purge api for deleting data. There is a table parameter if you want to delete data from a special table. But remember that the data is not deleted immediately, there are some days delay.
