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…)
+1 for this request.
@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 
This will not fix graph with wrong values.

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.
I have been looking for that feature too. If this was so unimportant Adafruit won’t have this in their service.
For instance, I have nice temperature graph and one single misreading messing all things over. It could happen once at week, or month, but still I have bad visualization and I have to choose from two: leave it as it is, or delete all data and start everything all over again.

+1 for this request and uploading data from CSV (like historic data or corrected historic data)

I need this as well. One misread make a mess in the graphs.
Closing very old topic as Blynk has already stated no further development likely on this original version
