After finding some time, I finally managed to solve this. I just needed to read the chart wiki a bit more careful. The result is now like this:
The snippet from the graphs.conf as follows: [[[outTemp_avg]]] zIndex = 3 name = Mittl. Temperatur color = orange observation_type = outTemp aggregate_type = avg [[[[marker]]]] enabled = true radius = 4 What was needed, was only the definition of the observation_type and aggregate_type. However, one issue is remaining. I tried to scale the the yaxis for the temparture by: yAxis_min = -5 yAxis_max = 40 This leads to the graph above. I think that yAxis_min does not accept negative values. Correct? If I change to: yAxis_min = 0 yAxis_max = 40 Then everything works as expected. Any idea how to solve my remaining issue (if possible)? -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
