Drawing X and Y axis scales with Skia

[tabupl]

Hey, I'm creating a chart with Skia (and d3) and I have a problem with generating correct Y/X axis scales.
The chart has a couple hundreds of data points, so I can't just show value of every datapoint on the axis, I need a "normal" scale (eg. Y axis: 0, 10, 20, 30...; X axis: 8:00, 8:15, 8:30...).

I know you can generate such axes with d3, but how can it work with Skia? (Or maybe you know a different method?).

PS. I have one additional problem, but since it's not the main issue here, I'll just leave it and maybe someone would know: Is it somehow possible to interpolate chart lines with different amount of datapoints? (I tried some solution with Flubber posted by @wcandillon, but it didn't seem to work for me). Although the maine issue here are the axes for now 🤞
