I use a SuperChart Widget (Android) with two DataStream objects.
I would like to change the DataStream names, from hardware (NodeMCU) programmatically with Blynk.setProperty or something. Is that possible? SuperChart does not even look to have a handle (Vx). Any link which explains its properties will be highly appreciated.
Best Regards

Hello. This is not supported. Datastream is something that supposed to be persistent.
Why?
Thanks Dmitriy. I see, i shall find some other workaround.
Costas, the reason i want to name datastreams from hardware, is that the application has a basic skeleton and a standard program flow, but the names and some other properties change according to the client specific demands. For example a Gauge widget for temperature readings has a blue color if it is a freezer application, or yellow if it is above zero. It has a label depending on it’s place in the plant. for example it could be “Freezer” or “Raw material” or “Milk Tank” etc.
Names, colors etc are stored in EEPROM. They are configured on site during commissioning, with a simple WebServer and specific Forms. It would be very convenient to correlate the name “Freezer” of the Gauge with its DataStream object, so when i change the name, the change will be automatically reflected in the name of the relative graph.
Maybe in the future, DataStream label could have by default the name of its Virtual pin it draws.
Sounds like a good idea.
