Multiple temperature sensors (DS18B20) graphed from one Pi
I'm wanting to have multiple temperature sensors from one Pi sending temperature readings to one graph. This will create a graph with a number of lines showing the trend for the different sensors.

This is already a feature. Configure any line graph and you can add multiple items to it. You can also create a new tile and add a number of things to it. I have the same sensor data replicated on six different tiles, each displaying it with others in different ways.
