Graphs with the same unit should use the same scale

[riccardomurri]

Expected behaviour

I would like to be able to compare readings on graphs showing temperature at a glance: if the bar on the disk temp is higher than the CPU temperature graph, then it should mean that the disk temperature is higher than the CPU's.

Actual behaviour

Each graph is scaled separately according to the sensor's min and max values, making graphs useless without hovering for reading the actual values. The screenshot shows a disk temperature graph (left) seemingly higher than the CPU temperature graph (right), but hovering reveals that the opposite is true: disk is at 45 °C and CPU is at 58 °C.

Steps to reproduce the behaviour

On my Thinkpad X1 Carbon, enable all temperature sensors from libsensors.

I can confirm that something is wrong with the graph. One of my disks which has 30°C usually is shown higher than CPU temp 38°C, when i choose the graph, And my M2 disk won't shown.
All works fine when i select icon + value, which is my preferred setting.
Btw. thew command sensors will show you the correct values in terminal.

It's not a bug, since all semiconductors have a specific safe operating area and junction temperature.
In screenshot, you only have to worry about the sensors which are filling the entire area of the graph.
