Neutral Gauge - Zero at 12 O'clock

[fitzer]

Imagine, if you wil, a Guage that has a needle that points straight up, with a value of 0. To the left, you have negative voltage up to -5. To the right, positive voltage, also up to 5. The neutral position of this gauage is zero. Any deviation from 0, will be either a positive or negative number.

How do Imake a gauge in Grafana perform in this manner. The guges here all seem to start on the left side, and start at zero.

I need this feature too. Example: I’d like do visualize my solar facility. The battery storage has a current power range from -2.5 kW (discharging) to 2.5 kW.
Did you manage to solve this somehow? If not, how could we make a feature request?

set your min and max values to -2.5kw and 2.5kw respectivly. this will put 0 in the 12 o’clock position.

If you want to show peaks past 2.5kw in either direction, then increase min/max accordingly.

Ok, let me illustrate with pictures what I mean:
Gauge as it is with min -2.5, max: 2.5:

The 0 is at 12 o’clock, but the bar starts as -2.5.

Gauge as I would like to see it:

0 is at 12 o clock and the bar starts also there.

Did you ever get an answer. I’m beating my head against the same desire / need

@eabyrd1506 Welcome to the Grafana forum.

Have you seen these two ideas that I made in another post? Best way to report both negative and positive values - #4 by grant2

[sfranzis]

Yes, that’s how it works all the time and it simply doesn’t look convenient.
But there is a reply under your post, that’s just another mockup of my post.

We know this is not implemented in Grafana today and the intention of this post was a feature request. Is there another channel where to post feature requests?

Hi Stefan. I think this is how the Grafana team wants to receive feature requests…

F.A.Q. - Feature requests as GitHub Discussions

Over the next few weeks, we’ll be moving all new feature requests to GitHub Discussions as noted both on the forums here and on GitHub. As Grafana’s community of users and contributors has grown, it’s become imperative that we improve how we engage in feature discovery, development and delivery. This will be a living F.A.Q. to address questions and process modifications as we roll out this change. Please read the notice if you haven’t. F.A.Q. Q. How do I make a feature request? Create a disc…

I requested it in GitHub already:

Setting the neutral-point of a gauge · Discussion #38273 · grafana/grafana

[yosiasz]

Have you looked into creating this via your own svg using the SVG plugin?

[sfranzis]

No, but I started fixing it on my own.
Here a before/after compare:

[revilo951]

How did you manage to achieve this? It looks excellent.

[sfranzis]

Cloned the source code from Github. Then implemented and build it.
Now I have to to a pull request and hope they’ll accept it.

[sfranzis]

Pull request issued:

Setting the neutral-point of a gauge #38273
