導入
物理実験や卒業研究のときにgnuplotを用いる人々が
レポート,卒業論文などを書く上で困らない程度にgnuplotを使えればと思い書いていきます.
ネット探してもあまり見つからなかったので
とりあえずテンプレが欲しい人向けテンプレ
gnuplotの情報って調べても出てきづらいので,
愛用しているテンプレートを載せます.
.gnuplot

前提情報
もっと前に書くべきだとは思いますが動作環境などの情報です.
動作環境
Ubuntu 24.04.1 LTS
or
Ubuntu 24.04.1 on WSL 2.3.26.0 (Windows 11 Home)
gnuplot version
$ gnuplot --version
gnuplot 6.0 patchlevel 0
OSごとに.gnuplotファイルの扱いが違ったと記憶しており, 筆者の環境ではホームディレクトリにこのファイルをおくと対話形式(スクリプトファイルなし)でもこの設定になります. ただ対話形式でgnuplotを用いる場合png出力にするメリットがないのでスクリプトファイルのテンプレートとして用いるか,termをpngcairoからqtやwxtに変えたほうがよいと思っています.
.gnuplot
- set terminal pngcairo enhanced size 707,500
+ set terminal qt size 707,500
+ set terminal wxt size 707,500
ちなみに縦横比707, 500はただの白銀比です.自由に変更してください.
テンプレートのマニュアルもどき
terminal
前述の通り, texに図を貼ることを想定しているのでpngでの出力をオススメします.
凡例にギリシャ文字を使うため enhancedを入れてください.
また, 出力ファイルを定めないとグラフは作れないのでplotの前くらいで
set output 'xxx.png'は必ずつけてください
font
レポートに貼る場合, Arialがかなり見やすいと思います, 太字ならなおよい.
目盛り,ラベルなどの設定をここで行っています.コンマの後の数字を変更することで大きさを変えることができます.ちなみにgnuplotでは文字列の結合は.を用います.
preview
出力させる画像に対し,グラフ画面がどれほどの大きさを占めるかを決めます.
その下にxlabelやylabelの位置の調整もここで行っています.
また, メモリの見え方の設定もここで行っています.ここで大事なことは, 桁数を統一すること.
有効数字に厳しい世界なので,小数第何位まで書くなどは必ず統一してください.
line
線の太さを2ptに設定しています, 1じゃ細すぎるので
またカラーリングを10種類定めました.見分けはつく程度のカラーリングです.
実際にplotする
データファイルの名前が日付などで統一されている場合,ベースを文字列に格納したほうが汎用性は高いです.
また出力する画像が2種類以上の場合も,作成日や実験内容などでベースを作ると都合がよいです.
test.plt
#plot area-
OUT_BASE='basename.png'
INPUT_BASE='inputfile'
set output '01'.OUT_BASE
plot INPUT_BASE.'01.dat' u 1:2 w l lt 1 title 'xxxx'
set output '02'.OUT_BASE
plot INPUT_BASE.'02.dat' u 1:2 w l lt 1 title 'xxxx', \
plot INPUT_BASE.'02.dat' u 1:3 w l lt 2 title 'yyyy'
では実際にplotしてみます.MD計算から得られた物理量をplotする例です.今回は時間に対する運動エネルギーとポテンシャルエネルギーをplotします.

xrangeなどはgnuplotにまかせています.横軸をナノ秒で書きたかったので,定数per_ns=100,000で割っています.作ったグラフを見てみます.
ちゃんとした論文はわかりませんが卒論程度ならこれでも怒られないと思います.
グラフのタイトルはグラフに書かずtexのキャプションに書くのがよいでしょう.
