Temperature limitation in graphs?

[Billy]

I'm logging my heating and solar data via a plug-in which is running well in Meteohub.
Problem:
Solar Collector temperature which was today 96 °C
was limited in GNU-Plot to 90°C Maximum.(attachment)
The data itself was correctly logged.
Is this a known limitation?

Thanks for your answers.

Did you set the maximum value in the graphic definition to 90°C?
Which plug-in do you use? I'm logging the hot water of my heating with a 1-wire sensor, no problems with the highest temperature of 94°C.

1. The maximum value in the graphic definition is not limited (not set)

2. I'm logging 17teen data and temperatures via rs485/rs232 connection to the heating controller.

3. Data acquisition done by a perl script.

What value are you plotting and using what time buckets?

If you are plotting the basic sensor value then even with the smallest bucket size (5 minutes) there will be some averaging taking place, which will have the effect of 'smoothing' the data. The bigger the time bucket, the greater the smoothing effect.

Could that explain what you are seeing?

Not really. At the moment no idea.
I'll check this again when th sun is shining longer to get more time for investigation.
