Is there a workaround to get a center zero gauge or histogram? I want to monitor/report on Net Energy. If generation from solar panels exceeds consumption then we are exporting (-ve) otherwise we are importing (+ve). I have seen other questions on centre zero guages but not found a way to to do it…

Hi guys, my implementation has been released with Grafana 9.3.0. See Gauge-Options, input “Neutral” Hope you like it :slight_smile: Stefan

Welcome to the forum. What is your datasource and which version of Grafana are you using?

Hello Grant, thanks for responding Datasourse is influxDB v1.8 which receives data from my energy monitor (IoTaWatt) Grafana version is 7.5.5 What I am aiming for is a dial that runs from (say) minus 10Kw to + 10kw with zero in the centre. The color (reading) should then from the centre towards t…

I think this works if you upgrade to Grafana 8.1: [image] In InfluxDB 2.0 Data Explorer: [image]

Thanks for coming back so quickly, The Data Explorer view is close and might do the trick. On your normal gauge the colour is starting at -15 (the gauge minimum) and not at zero. Here are a couple of examples (I’ve edited your 6.73 gauge) to show what I am trying to achieve. [center_zero_example…

Hmmm…I cannot find a way in Grafana to change the bar as you indicated in your screenshot: [image] Maybe a future update of Grafana will address this? (any Grafana staff want to to chime in?) I do not know if InfluxDB 1.8 offers any charting tools like 2.0 does, but give it a try, or post your qu…

Implemented it. See my pull request: Setting the neutral-point of a gauge by sfranzis · Pull Request #53989 · grafana/grafana · GitHub

@sfranzis Thank you coming back to this thread to let us know. Hopefully it will be merged and available to use soon.

Hi Stefan, how can I implement your workaround in Grafana?

Thanks for letting us know. I couldn’t find the setting (9.3.1 running on Raspberry Pi) but when I put ‘neutral’ in the ‘Search options’ box I found it (not sure if I just missed it the first time). It is there in the main options now. The documentation doesn’t appear to have been updated yet. Fr…

Thanks for your feedback. You can also set neutral to non-zero values. Example use case: monitoring line frequency. Min:49.5, Max: 50.5, Neutral: 50.0

I think this works if you upgrade to Grafana 8.1:
