feat(plot_lines): use ordinal x-axis for integer tick labels#12
Merged
Conversation
Switch x-axis encoding from quantitative (Q) to ordinal (O) to guarantee integer-only tick labels. The x-axis represents a step/epoch index, making ordinal encoding semantically correct. Quantitative encoding with tickMinStep was stripped by vegafusion during Vega compilation. Also adds IPython cell markers (# %%) to test files for interactive visual verification in IDEs with ipykernel support. Each plot function can be visually inspected by running the corresponding cell. Build: adds ipykernel dev dependency for cell execution.

Summary
plot_linesx-axis from quantitative to ordinal encoding, ensuring integer-only tick labels for step/epoch indices# %%) to test files for interactive visual verificationDetails
The x-axis in
plot_linesrepresents discrete step indices. Quantitative encoding withtickMinStep=1was stripped during vegafusion compilation, causing fractional tick labels. Ordinal encoding is semantically correct for this use case and guarantees integer labels.The IPython cells allow each plot function to be visually verified by running cells directly in IDEs with ipykernel support.
