Allow resetting of metadata plots

[clayheaton]

In handling a last-minute request, I implemented a flow that, among other things, outputs an integer as metadata, for tracking load of users into a system. Following initial deployment and running, I learned more about timing, etc. Unfortunately, the metadata plot was looking janky because of the initial deployment schedule. Not knowing how to remove the data recorded in the first runnings, I updated the flow to create a new variable, hoping the old plot would disappear.

Now that things have stabilized, I'd like to be able to reset the top plot to get rid of the noise and to remove the bottom plot. I do not see where this is possible through the UI or in code. Does it require a manual database removal of rows?

This is a suggestion for a feature that allows for the resetting of metadata plots on assets.

Yes you would remove the run records from the database. There's an explainer how to do that in #12047
