solow-graphics

Statistical-graphics helpers that compute the data behind a plot and render it through the [solow_viz] SVG backend. Every routine returns both the rendered [Figure] and the computed arrays, so the numerics can be tested independently of the (intentionally un-pixel-exact) SVG output.

Provided:

• [ProbPlot] / [qqplot] — theoretical vs. sample quantiles of a probability plot, plus the fitted reference line ([QqLine]).
• [plot_acf] / [plot_pacf] — the (biased) autocorrelation and the Yule-Walker partial autocorrelation, with a white-noise confidence band.
• [plot_resid_fitted] — a residuals-vs-fitted diagnostic scatter.

use solow_graphics::ProbPlot;
let data = [-1.2, 0.3, 0.1, 1.4, -0.7, 2.1, -0.2, 0.9];
let pp = ProbPlot::new(&data);
assert_eq!(pp.sample_quantiles().len(), data.len());
let line = pp.qqline_regression();
let svg = pp.qqplot().to_svg();
assert!(svg.starts_with("<svg"));
let _ = line.slope;
