I have a gauge set as a doughnut.

This is happening now and then with certain values.

Notice how the green is ..... deformed at the end of the end of the arc.

Yes, but it will be in the underlying justgage library so would need to be raised there.

Ok, but where is “there”?

Yes. Ok.

So looking at the link in the reply, may I take it as understood you are the “owner” of said library?

(I am going to have to get set up with github soon, it seems)

No, that library is not ‘owned’ by anyone here.

It would help if you shared some details in how you have that guage configured so we can try to recreate.

I only asked because when I opened the link and went there I saw a picture the same as the one in the post.

So, if the same picture was on github and the person…

Ah!

Ok. Got it. Sorry. Graph data/settings to come later.

Ok, this is the code.

Just checked again and it is REAL TIME and happening (again) now.

```

Basically I am sending temperature values to the gauge.  
If it is around 37.9 it give this error.

UPDATE  
It starts at 35.4 and ends at about 42.6 as far as I can see.  
I put an slider node and set the range from 0 to 800 with a step of 1.  
So on the slider at about 354 - 426 it happens.

So do what Dave told you to do - go to GitHub for the ‘justgage’ library and open an issue. There is nothing more anyone here can do about this.

If you don’t know how to do that, try googling ‘GitHub tutorial’ and learn.

It might be useful for submitting the issue to know whether it happens with different browsers.

Been, done.

But I had to “join” github first.
