  1. Gnuplotの使い方 ～基礎演習４　　用～

  2. 基本設定１ 必須 • set terminal png • set output “出力ファイルパス名” • set title “タイトル” • set xlable “横軸名” • set ylable “縦軸名” • set xrange [-10:10] • set yrange [0:100]

  3. 基本設定２ • set xtics “目盛間隔” = set {x目盛|y目盛}tics • set m{x目盛|y目盛}tics (大きい目盛分割） • set grid (グリッド線を引く) • set logscalex • set logscale y

  4. 凡例 • set key left bottom • set nokey

  5. 色 • set style line 1 lt 1 lw 4

  6. 線種

  7. symbols

  8. 関数プロット • plot sin(x),cos(x) 　 （複数プロット） • plot sin(x) title “sin”, cos(x) title “cos” • splot x**2+y**2 (3次元プロット) • 等高線のプロットなども可能

  9. 実験データをプロットする１ • lines(折れ線グラフ) • dots(散布図) • points(散布図) • linespoints(折れ線グラフ) • boxes(棒グラフ)

  10. 実験データをプロットする２ • plot “file.dat“ \ index 0:0 \ using 1:2:3 \ title “凡例に表示されるタイトル１“ \ with points, \ “file.dat“ \ index 1:2 \ using 1:2:3 \ title “凡例に表示されるタイトル２” \ with lines
