From c91872bc46a66bab72d936d19b2f84b2d3292114 Mon Sep 17 00:00:00 2001 From: Zhanibek Date: Tue, 12 Mar 2024 23:53:38 +0900 Subject: [PATCH] Road to plots 2.0 (#4866) * remove deprecated backends * move GR to extension * make plot3d work * make heatmap work * factor components into modules * finish Surface module * export is_horizontal from Fonts * start refactoring Plot, Subplot, etc. components * change version * continue module shuffling * continued refactoring * remove orientation * minimal usable state * format * remove makekw * anything up to Segments * move series stuff from utils * use Arrows * create Colorbars module * move axes stuff (precompiling state) * let's relax deps and add them back later if needed (macOS issue) * only 2 tests fail now * restructure extension logic * remove unicode for now * GR extension * update deps * init step of gr * proper init of GR * for now manually activate the backend * road to fixing gr * revert some changes * fix import exports * fix measures * clarify name space * might need to be reverted, shape->Shape (too confusing_ * return lost wrap * types and modules * fix more things * add gr function * remove stale and fix naming * added unicode backend * unicodeplots works * update runtests * only use explicitly imported names in backends * rename wrap to protect * remove pre post imports, move to alignment jl * alignment jl * remove comments * fix typo * finally fix InputWrapper, misc changes * import overloaded, namespace fix * fixing per backend exceptions * alost all tests are passing * fix exports * trying to fix project toml * try to resolve deps * move other backends to the extensions * start pgfplotsx * add backends to weakdeps * recover * already defined * fix GR plot area method overload * plotarea methods are overloaded in layouts.jl * more fixes * fix test * namespace fixes * fix namespaces * revert later * rm pyplot * remove requires * add PGFPlotsX imports * bump julia compat * create runtime functions for all backends * improve error handling * pgfplotsx loading * get tests running * fix names, skip StatsPlots examples * test on 1.10 * remove pyplot remainings * don't test julia < 1.9 * run julia formatter * add pythonplotbackend * fix init python plot * gaston working * reorganize plotly backends * update kaleido compat * format * remove PlotlyBase compat * make default backend functional * make plotly functional * naming and PlotlyJS * get gaston running * run more tests * move dev in ci * dev both at the same time * fix syntax * don't dev twice * only load Gtk if not on CI * add missing using statement for PlotlyJS * more imports * move merge_with_base_supported to Commons * make Plotly module * skip non-working tests * fix filtering * format * invert filter * fix pgfplotsx warning * don't test Gaston * fix cgrad missing * format --------- Co-authored-by: Simon Christ Co-authored-by: Simon Christ Co-authored-by: = <=> --- .github/workflows/ci.yml | 29 +-
