Not enough data to display

Anybody else having problems with the History Graph?

I’ve had my app running for hours and the graph is still saying “Not enough data to display”.


Problem is at your end.

You could provide some more info than you have…

Are you sure your value is send to server? How do you write value?

  Blynk.virtualWrite(V7, String(Buffer1) + "%");
  Blynk.virtualWrite(V6, String(Buffer2) + "℃");

It’s OK. I can see where i’ve gone wrong. I made a change to the format of the temperature and humidity and they are now strings instead of numerals so the graph won’t show them. It’s fixed now.

@TheArduinoGuy exactly. We recommend to do formatting on app side. It is more flexible. Have a look into labeled value display.
