polars VS plotters

This is because 0.1 is in actuality the floating point value value 0.1000000000000000055511151231257827021181583404541015625, and thus 1 divided by it is ever so slightly smaller than 10. Nevertheless, fpround(1 / fpround(1 / 10)) = 10 exactly.

I found out about this recently because in Polars I defined a // b for floats to be (a / b).floor(), which does return 10 for this computation. Since Python's correctly-rounded division is rather expensive, I chose to stick to this (more context: https://github.com/pola-rs/polars/issues/14596#issuecomment-...).

That turned out to be related to pola-rs/polars#11912, and this linked comment provided a deceptively simple solution - use PARSE_DECLTYPES when creating the connection:

plotter-rs Cairo backend: Specific backend to interact with a gtk-rs DrawingArea widget.

I would also look at plotters https://github.com/plotters-rs/plotters to replace mathplotlib. Unfortunately, I'm not aware of any library for image transformations/augmentations.

Have you looked into plotters https://github.com/plotters-rs/plotters ? I think it should be possible to integrate it into an app.

About plots, besides plotly, take a look at https://github.com/plotters-rs/plotters and https://github.com/milliams/plotlib

I'd recommend plotters, I've only used it for it's drawing api and I found it quite nice for text rendering.

For those who do not know about them, polars is a data frame crate for Rust and Python. It is also the fastest data frame library, according to benchmarks. Plotters is a crate for data visualisation. Both are the equivalents of pandas and matplotlib from the Python ecosystem. However, the integration with matplotlib in pandas has no equivalent. I would like to propose an effort to integrate polars with plotters, either by modifying the existing codebases, or creating a new bridge crate. I would love to hear opinions about this from the widder community.
