Color thresholds off when near zero

[OingoFan55]

Running: v0.13.0 on Home Assistant: 2025.7.3

Trying to figure out where I'm going wrong on using color thresholds for indoor/outdoor temperature differences. When positive (above zero), I want the line to be red, when below, I want blue. I added a second sensor (set to zero) so I can set a gray line between them both. There is some type of clipping going on to where the line turns blue even though it has a positive value (such as 2.32). I did notice that these point colors are correct when hovered over (when it makes the points big).

Where am I going wrong?

Here is pic to show colors are correct when hovered over.

This is a known issue. Cannot give you a link, it is already registered here.
Not about “near zero”, it is about differences between a colored line and a colored point.
No workaround yet.
Is one of the most prioritized tasks to be performed.

Good to know! Thanks!
