Gauge swings L/R from centre


I'd like to display a guage that shows energy flow into/out of the house.

At zero flow, the guage points upwards (12 o'clock) with a value of 0

At negative flow (exporting to the grid) I want the pointer to rotate anticlockwise towards the full scale deflection of 6 o'clock, with a green colour extending from the 12 oclock postiion anticlockwise to the left.

At a positive flow (using energy from the grid) I'd like the pointer to rotate to clockwise from 12 o'clock and show the flow (in a red colour),

Does anyone know of a UI tool that can do this or if I can modify the guage node to do this?

It would also be used for example to show political swings to the left-right.

Again, the colour starts-extends clockwise/anticlockwise from the 12 o'clock position.

Thanks for any help.

Definitely not possible with regular gauge, but the Artless Gauge has option "differential mode". But you'll miss the needle.

If you are looking for gauge with needle, may be some JavaScript library can provide what you need but I haven't tried any.

Much better option will be to create the gauge which satisfies all your needs. There is a good starting point shared to get things going ...

Hi hotNipi,
Thanks for this. The DIY guage looks very impressive and I will see what I can come up with. Cheers Rich

With some simple "scaling" of the values the standard gauge should do this.
IE shift them to the right so the balance point becomes 50, have the gauge run from 0 to 100 (or whatever values suit) and set the sectors accordingly. Issue will be the text reading will be off as well... but hide it and put you own label under it...
