From b890c83a9e03c11b689fc4d11df32bafbde59e6b Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Wed, 10 Jun 2026 01:49:31 +0000 Subject: [PATCH 1/5] feat(pygal): implement acf-pacf MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Regen from quality 85. Addressed: - Canvas fixed to 3200×1800 (was 4800×2700) - Added ANYPLOT_THEME support for light/dark rendering - Replaced non-Imprint colors with Imprint palette (#009E73 for significant bars, INK_MUTED for non-significant, ANYPLOT_AMBER for CI lines) - Fixed output filenames to plot-{THEME}.png / plot-{THEME}.html - Fixed background to Imprint page surfaces (#FAF8F1 light / #1A1A17 dark) - Updated font sizes to style-guide values (title=66, label=56, major_label=44) - Added sys.path fix to prevent self-import when script name matches package name --- .../acf-pacf/implementations/python/pygal.py | 169 +++++++++++------- 1 file changed, 102 insertions(+), 67 deletions(-) diff --git a/plots/acf-pacf/implementations/python/pygal.py b/plots/acf-pacf/implementations/python/pygal.py index 5582e97374..573124ee40 100644 --- a/plots/acf-pacf/implementations/python/pygal.py +++ b/plots/acf-pacf/implementations/python/pygal.py @@ -1,9 +1,17 @@ -""" pyplots.ai +"""anyplot.ai acf-pacf: Autocorrelation and Partial Autocorrelation (ACF/PACF) Plot -Library: pygal 3.1.0 | Python 3.14.3 -Quality: 85/100 | Created: 2026-03-14 +Library: pygal 3.x | Python 3.x """ +import os +import sys + + +# Remove this file's directory from sys.path so `import pygal` resolves to the +# installed package, not this script (which shares the same name). +_this_dir = os.path.dirname(os.path.abspath(__file__)) +sys.path = [p for p in sys.path if os.path.abspath(p or ".") != _this_dir] + import io import xml.etree.ElementTree as ET @@ -15,7 +23,29 @@ from statsmodels.tsa.stattools import acf, pacf -# Data -
