Superchart no historical data

Hello, I have a problem with the historical data of the Superchart. I put the Blynk local server(ver. 0.41.5)on my Raspberry Pi3, everything seem to be working fine but when I use the Superchart I can only see the live data. Even leaving the program on for days I can’t see the historical data, they are not stored. Please let me know what I need to do to allow historical data on local sever.

Thank you in advance.

You must have other display widgets assigned to the vPins that you want SuperChart to historically show.

Thank you, I solved, I sent the data to the server in a wrong format and for this reason they were not saved!
