Extra sensor real time graphs

Hi Brian,
These are really working for my WMR extra sensors!

There seems to be something else on the graph with a constant 0C and 0% humidity - they are the grey and yellow lines on my graph - can you make them go away?

Also, I still get the spikes for the realtime and autoscale extra sensor graphs when WD restarts.

Finally is there a way to reduce the temperature scale - all my extra sensors are indoor and it does not make sense to go from -26C to +34 C - I’ve played with the up and down arrows, but that shifts the humidity too and change the min temp just causes the max to move too, the range does not change.

Cheers
Ian
