gnuplotでグラフ画像を量産したい． というわけで，Homebrewで環境をつくる．
参考は，gnuplotをHomebrewからインストールするときの手順 - Qiita と OctaveをMacにインストールする [X11 or AquaTerm] - フェムトセカンド (@melonsode blog) です．
aquaterm にするか X11 にするかだけど，あまりアプリは入れないひとなのでXcodeとかのためすでに入れてる X11 を使う方針でいきます．
gnuplot: stable 5.0.1 (bottled), HEAD Command-driven, interactive function plotting http://www.gnuplot.info Not installed From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/gnuplot.rb ==> Dependencies Build: pkg-config ✔ Required: fontconfig ✔, jpeg ✔, libpng ✔, libtiff ✔, readline ✔ Recommended: gd ✘, lua ✘ Optional: pdflib-lite ✘, qt ✘, wxmac ✘ ==> Options --with-aquaterm Build with AquaTerm support --with-cairo Build the Cairo based terminals --with-latex Build with LaTeX support --with-pdflib-lite Build with pdflib-lite support --with-qt Build with qt support --with-tests Verify the build with make check --with-wxmac Build wxmac support. Need with-cairo to build wxt terminal --with-x11 Build with x11 support --without-emacs Do not build Emacs lisp files --without-gd Build without gd support --without-lua Build without the lua/TikZ terminal --HEAD Install HEAD version
X11を使用し，emacsは使わないのでそれを指定． gdとluaも入っちゃうけど，まぁいいか．

This is, for now, unavoidable.

たくさんのCSVからグラフ画像を書き出したいので，ShellScriptからgnuplotを動かします． というわけで，設定を追加．
export GNUTERM=x11
あとは，シェルスクリプトによるデータ処理 をみてかきました． いまは，jpeg出力にも対応してるので，たくさんつくって一気に確認ができて楽ですね．
