From 0f631b97ea610718043cdc9b95720338f16269f1 Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" Date: Wed, 3 Jun 2026 18:08:16 +0000 Subject: [PATCH 1/5] feat(highcharts): implement spectrogram-mel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Regen from quality 90. Addressed: - Canvas fixed to 3200x1800 (was 4800x2700 — hard contract violation) - Added ANYPLOT_THEME env var support with full theme-adaptive chrome (PAGE_BG, INK, INK_SOFT, ELEVATED_BG) - Replaced hardcoded magma colormap with Imprint sequential (green→blue, imprint_seq) - Fixed output to plot-{THEME}.png and plot-{THEME}.html (was bare plot.png/plot.html) - Added CDP Emulation.setDeviceMetricsOverride for authoritative viewport sizing - Added PIL dimension safety net for exact 3200x1800 output - Removed unused annotations module download (CQ-03 fix) - Fixed tooltip pointFormat to valid Highcharts syntax (LM-01 fix) - Updated title to anyplot.ai format and correct font sizes (title 66px, axes 56px, ticks 44px) - Preserved: rich audio synthesis, section labels/dividers via renderer API, mel filterbank --- .../implementations/python/highcharts.py | 210 ++++++++---------- 1 file changed, 96 insertions(+), 114 deletions(-) diff --git a/plots/spectrogram-mel/implementations/python/highcharts.py b/plots/spectrogram-mel/implementations/python/highcharts.py index 97e6e05a34..cb456ac136 100644 --- a/plots/spectrogram-mel/implementations/python/highcharts.py +++ b/plots/spectrogram-mel/implementations/python/highcharts.py @@ -1,9 +1,10 @@ -""" pyplots.ai +"""anyplot.ai spectrogram-mel: Mel-Spectrogram for Audio Analysis -Library: highcharts unknown | Python 3.14.3 -Quality: 90/100 | Created: 2026-03-11 +Library: highcharts | Python 3.13 +Quality: 90/100 | Updated: 2026-06-03 """ +import os import tempfile import time import urllib.request @@ -13,31 +14,32 @@ from highcharts_core.chart import Chart from highcharts_core.options import HighchartsOptions from highcharts_core.options.series.heatmap import HeatmapSeries +from PIL import Image from scipy.signal import spectrogram from selenium import webdriver from selenium.webdriver.chrome.options import Options -# Data -
