Tutorial for 'Data Visualisation' doesn't work about up4

[DanW97]

What branch are you using?

[Aran55336]

Just the default upppp branch I believe, I followed the instructions on there for download.

Ah, that'll be the issue.

The plotting interface is in the middle of a major rework into a saner entity. I'm working on it currently, I've just had a lot of stuff on my plate lately, so I haven't had time to finish off the rework.

For now, please use the new-plotting-interface branch. The way to use the newer iteration of the plotting interface can be found in tests/test-interface.py is as follows:

plotter = up4.Plotter2D(vec_field)

fig = plotter.unit_vector_plot(axis, selection="depth_average")
fig.update_layout(width=600, height=600)
fig.update_xaxes(title="x position (mm)")
fig.update_yaxes(title="y position (mm)")

The key difference is that the two plotters focus on whether the plot is 2D or 3D, introducing Plotter2D and Plotter3D. For Plotter2D, you have the following arguments you can pass:

• axis (0, 1, 2)
• selection ("depth-average" or "plane")
• index (only required for "plane" selection)
• scaling_mode ("max", "min", "minmax", "half_node", "full_node")
• scaling_args (has to be a list)

I'll leave this issue open until the rework is merged into the default branch.

I had to reinstall as I think the new plotting interface was updated recently (tried running after switching branches but it said the Plotter2D command didn't exist), but now it doesn't seem to reinstall. I get this error when building wheels for up4 " error: cargo rustc --lib --message-format=json-render-diagnostics --manifest-path Cargo.toml --release -v --features 'python pyo3/extension-module' --crate-type cdylib -- failed with code 101". I have tried reinstalling rust to see if it was out of date but no difference.

Interesting. What version of Rust are you using?

Can you try running cargo clean and pip uninstall up4 to ensure that you are starting fresh. And then when installing from the new-plotting-interface branch run:

RUST_BACKTRACE=1 python3 -m pip install . -vvv > install.txt 2>&1

and attach the created file.

[Aran55336]

Of course, attached is the file!
install.txt

Hi @Aran55336, once #34 is merged, hopefully your issues are all resolved!
