linearGradient with three colors?

Maybe a description of what's not working?
I'm not going to learn anything from this stamp-sized picture.

i am saying that gradient of three colors doesn't apply. its showing like the picture i sent. but it should be from one direction to the other like in a line. but its treating it as a circle starting from bottom to top.

it should be a gradient like guage meter like this

but obviously with your style

Unfortunately, that's how lineargradient in svg works, it's a tonal transition between colors it's not a bug, that's how it works.
If you want it to look like your example, you'll have to use a different library, unfortunately.
Gradient doesn't work on svg circle elements. Have a look here maybe it will help you - svg-multiple-color-on-circle-stroke
