Needle stays always at zero

[na-am]

Hi@all
i'm using latest grafana und installed yesterday d3 gauge plugin
datasource is influxdb ( select last(value) from hum )

the unit is not shown and the correct value of 37.0 isn't formatted at 1 decimal

[briangann]

can you show the metric query inspector output?

Hi Brian, hope, thats what you wanted to see: xhrStatus:"complete" request:Object method:"GET" url:"api/datasources/proxy/1/query" params:Object db:"thp" q:"SELECT last(value) FROM hum" epoch:"ms" data:null precision:"ms" response:Object results:Array[1] 0:Object statement_id:0 series:Array[1] 0:Object name:"hum" columns:Array[2] 0:"time" 1:"last" values:Array[1] 0:Array[1549712333926,33] Von: Brian Gann<mailto:[email protected]> Gesendet: Freitag, 8.

The response looks fine, can you try creating a new panel with no changes (all default) and the same query?

I made a similar query with influx and it shows the data (with decimals and units)

Surprise, surprise, Brian, the needle is moving when I Change the select statement to COUNT!!!

I am getting similar error whenever the value is less than zero, needle stays at bottom. Any idea

Hi @briangann I have the same issue the gauge always stays at the maximum value.
Grafana version: Grafana v6.2.5 (6082d19)
D3 gauge version: 0.0.6

Limits i have given Min 0 and Max 100. I have tried giving MAX 700 too but still stays at max value

Hello, I had same issue and same behaviour, needle moves only when I used count of measurements. Than I found, that the values that I tried to visualize are not integer or float... it was number but saved as string. So check your input if it is real number.

(Grafana 9.2.5) I get some strange behaviour dependent on decimals. Here the value is 0.499, and the units set to "Kilowatt (kW)"

When decimals set to "auto":

When decimals set to "0":

However, with decimals set to "1" the needle position is correct:
