How to keep points aligned ?

[ykm7788]

Hiya,

I found this tool useful but with a tiny issue:

I'm trying to plot a simple point ring with only one point at one position and I want them to be aligned at the middle of ring. I suppose this is controlled by "value", so I tried to use same "value", but it went wrong. It only works if I use different "value" but the vertical position of points become "random" then.

Then, I tried to use "stack" instead, they do keep aligned this time but it still went wrong if I try to set their color.

So I'm wondering how can I both keep them aligned and with different colors ?

Thank you for your help !
