Maximaで点をplotする

Last updated at Posted at 2015-04-24

plot2dを使ってdata.txtに書かれた値をplotする。

data.txt
0 0
1 2
2 4
3 6
4 8
5 10

こんな感じのdata.txtを用意する。左がx座標、右がy座標。

maximaを起動して

data: transpose(read_matrix("/path/to/data.txt"));
plot2d([discrete,data[1],data[2]],[style,points]);

これで、点がプロットされる。style,pointsを消せば、直線が表示される。
data[1],data[2]というのが、最初に取り込んだdata.txtの列を表しているので
この値を変えれば、どの列をどの座標の値にするかを変更できる(はず)
