History Graph Max variables

Hello.
Could you please advise if there is a limit on the number of variables that can be displayed in Graph History?
I am using iPhone IOS and Arduino MEGA. Using BLYNK server (no local server).

The widget limits to 4 but can I use two such widgets for a total of 8 variables. I have tried and the max I get is 4.
Also the BlynkWrite function (SendUpTime) times out after 20 minutes or so.

Thanks in advance

Hello.

Yes. do you have problem with that? Could you please describe why you can’t choose more 4 pins in another graph widget?
