Deleting values from history

#1

Hi, is there a way to safely edit/remove wrong/undesired values from the history of a variable, when running a local server?

Sorry, I was not clear enough. What I mean is to delete selected values.
It looks like using the suggested function would delete all variable data, am I wrong? (I didn’t dare to go on with the confirmation, as I don’t want to risk trashing “good” data…)

@s.degtyarev Assuming this is the part of the request for the +1 then don’t Erase data, just Export it CSV and use your choice of spreadsheet to view and manipulate the data to your heart’s content :wink:

No, but how often will the average Blynker ever really need or care to do that? I personally don’t see this as a priority idea that the Developers will put effort into… but who knows? Perhaps something for Local Server users as I can’t see it being a valid process (bandwidth wise) on the Cloud Server.

If I wanted perfected graphs of history… then the CSV and spreadsheet polishing is the way to go.
