Struggling to figure out a way to draw curves in Slint

[lbluee]

After some hurdles trying to figure out a sound approach to draw parametrizable slopes I've decided to ask here. The Path component doesn't allow loops, and feels restricting. It automatically centers the rendered curve, and it also truncates if the bounding area is too small, this is not reliable. So I guess it's about using Image then, but the quality is not on par with the rest, and no resizing. Is there perhaps something I'm missing?

slint is still pretty underdeveloped even being like 3 years old, so expect alot (i mean alot) of limitations and inconveniences like this. if im being honest i would probably suggest using a different gui toolkit for advanced cases like that in the meantime like dioxus

I wish we had an out-of-the-box graphs engine that we could use and share in the ecosystem, but I don't think that exists yet. Python folks can integrate matplotlib into Slint, but for Rust there's no such library, I think. We do have commercial users that use the Path element to draw measurement graphs (some of which that are rather complex), but the code isn't easy with Path - as you've noticed.

What library do folks use with dioxus?

It's still possible to do a line graph using the Path component, but like you mentioned, no loops. I put together an example that uses 20 fixed data points. Awkward but usable.

Right, I appreciate the example, but it's just too much friction to be considered usable at greater scale imo.
I'll wait until they streamline things a bit.
