Currently the graphs look like this:
Some improvements I see possible:
- The rounding on the Y-axis could be improved, e.g. only show the amount of decimals that the sensor is giving (e.g. if a sensor has 15.5 and 17, show everything with 1 decimal)
- The timestamp on the X-axis is unreadable because the string is too long, I would only put HH:MM instead of a long date
Some optional stuff:
- Indicate min/max value (e.g. red/green dot)
- Add average on graph
