Hi all, This seems to be a truetype font issue my plots were made without true type support. I noticed the difference between Alan plots and mine were not only in position and orientation but also in fonts used. I have a lot of true types fonts installed but for strange reason none is selected.
Hi António: PLplot's lack of access to system fonts on your platform is indeed a most peculiar result. You probably know this already, but just to remind you, PLplot users of TTF fonts can specify only generic fonts such as "sans" and "serif", and then it is up to device driver to find for a given UCS4 glyph request, the best system glyph that belongs to the generic family. For example, the cairo device driver uses a subset of the GTK+ suite of libraries to create plots, and that suite uses fontconfig to find the appropriate system glyph. And the qt device driver uses a subset of the QT suite of libraries to create plots, and that suite also uses fontconfig in the same way, but if fontconfig is not available it falls back to an emergency way of selecting glyphs that doesn't give very good results. So from your bad font results my guess is you either don't have fontconfig installed at all or it has a broken configuration. For what it is worth, here is a list of all packages I have installed that have anything to do with fonts. -------------------------------------------8<------------------------------------- irwin@merlin> dpkg --list |grep -i font ii aglfn 1.7-3 all Adobe Glyph List For New Fonts ii console-setup 1.187 all console font and keymap setup program ii fontconfig 2.13.1-2 amd64 generic font configuration library - support binaries ii fontconfig-config 2.13.1-2 all generic font configuration library - configuration ii fonts-adf-oldania 0.20110505-3 all Oldania font of the Arkandis Digital Foundry ii fonts-dejavu 2.37-1 all metapackage to pull in fonts-dejavu-core and fonts-dejavu-extra ii fonts-dejavu-core 2.37-1 all Vera font family derivate with additional characters ii fonts-dejavu-extra 2.37-1 all Vera font family derivate with additional characters (extra variants) ii fonts-droid-fallback 1:6.0.1r16-1.1 all handheld device font with extensive style and language support (fallback) ii fonts-font-awesome 5.0.10+really4.7.0~dfsg-1 all iconic font designed for use with Twitter Bootstrap ii fonts-freefont-otf 20120503-8 all Freefont Serif, Sans and Mono OpenType fonts ii fonts-freefont-ttf 20120503-8 all Freefont Serif, Sans and Mono Truetype fonts ii fonts-gfs-baskerville 1.1-5 all ancient Greek font revival ii fonts-gfs-porson 1.1-6 all Greek font (Porson revival) ii fonts-hack 3.003-1 all Typeface designed for source code ii fonts-lato 2.0-2 all sans-serif typeface family font ii fonts-lmodern 2.004.5-5 all OpenType fonts based on Computer Modern ii fonts-noto 20171026-2 all metapackage to pull in all Noto fonts ii fonts-noto-cjk 1:20170601+repack1-3 all "No Tofu" font families with large Unicode coverage (CJK regular and bold) ii fonts-noto-hinted 20171026-2 all "No Tofu" font families with large Unicode coverage (hinted) ii fonts-noto-mono 20171026-2 all "No Tofu" monospaced font family with large Unicode coverage ii fonts-noto-unhinted 20171026-2 all "No Tofu" font families with large Unicode coverage (unhinted) ii fonts-roboto-slab 1.100263+20170512-1 all Google's signature family of fonts (slab) ii fonts-texgyre 20180621-2 all OpenType fonts based on URW Fonts ii freetype2-doc 2.9.1-3 all FreeType 2 font engine, development documentation ii gsfonts 1:8.11+urwcyr1.0.7~pre44-4.4 all Fonts for the Ghostscript interpreter(s) ii gucharmap 1:11.0.3-1 amd64 Unicode character picker and font browser ii kbd 2.0.4-4 amd64 Linux console font and keytable utilities ii libfont-afm-perl 1.20-2 all Font::AFM - Interface to Adobe Font Metrics files ii libfontconfig1:amd64 2.13.1-2 amd64 generic font configuration library - runtime ii libfontconfig1-dev:amd64 2.13.1-2 amd64 generic font configuration library - development ii libfontenc1:amd64 1:1.1.3-1+b2 amd64 X11 font encoding library ii libfreetype6:amd64 2.9.1-3 amd64 FreeType 2 font engine, shared library files ii libfreetype6-dev:amd64 2.9.1-3 amd64 FreeType 2 font engine, development files ii libgraphite2-3:amd64 1.3.12-1 amd64 Font rendering engine for Complex Scripts -- library ii libkfontinst5 4:5.14.3-1 amd64 Tools and widgets for the desktop library ii libkfontinstui5 4:5.14.3-1 amd64 Tools and widgets for the desktop library ii libotf0:amd64 0.9.13-4 amd64 Library for handling OpenType Font - runtime ii libsdl-ttf2.0-0:amd64 2.0.11-5 amd64 TrueType Font library for Simple DirectMedia Layer 1.2, libraries ii libsdl2-ttf-2.0-0:amd64 2.0.14+dfsg1-3 amd64 TrueType Font library for Simple DirectMedia Layer 2, libraries ii libwoff1:amd64 1.0.2-1 amd64 library for converting fonts to WOFF 2.0 ii libxfont2:amd64 1:2.0.3-1 amd64 X11 font rasterisation library ii libxft-dev:amd64 2.3.2-2 amd64 FreeType-based font drawing library for X (development files) ii libxft2:amd64 2.3.2-2 amd64 FreeType-based font drawing library for X ii lmodern 2.004.5-5 all scalable PostScript and OpenType fonts based on Computer Modern ii t1utils 1.41-2 amd64 Collection of simple Type 1 font manipulation programs ii tex-gyre 20180621-2 all scalable PostScript and OpenType fonts based on URW Fonts ii texlive-fonts-recommended 2018.20181116-1 all TeX Live: Recommended fonts ii timgm6mb-soundfont 1.3-2 all TimGM6mb SoundFont from MuseScore 1.3 ii xfonts-100dpi 1:1.0.4+nmu1 all 100 dpi fonts for X ii xfonts-75dpi 1:1.0.4+nmu1 all 75 dpi fonts for X ii xfonts-base 1:1.0.4+nmu1 all standard fonts for X ii xfonts-encodings 1:1.0.4-2 all Encodings for X.Org fonts ii xfonts-scalable 1:1.0.3-1.1 all scalable fonts for X ii xfonts-utils 1:7.7+6 amd64 X Window System font utility programs -------------------------------------------8<------------------------------------- I find gucharmap (a GTK+ application) extraordinarily helpful in figuring out which of the system fonts that fontconfig will select for *any* unicode glyph. I highly recommend that you install that package and use it since it should be able to quickly find out independent of PLplot if fontconfig is working properly on your system.
