You can plot between varying area, when you define the scope.
plot [-5:10] 0.1*x^2tをラジアンとしてxの式とyの式を指定してあげることで円などの様々な曲線を描画できます。いろいろ試してみてぜひグラフを保存してみてください。
plot x=cos(t), y=sin(t)use "draw" command
draw line({x:0, y:0}, {x:5, y:5})It is possible to draw on the graph in figures of the straight line, the triangle, the quadrangle, and yen, etc. by specifying coordinates.
| Method | Function | Example |
|---|---|---|
line |
It draws in the straight line specifying two points. | draw line({x:0, y:0}, {x:5, y:5}) |
triangle |
It draws in the triangle specifying three points. | draw triangle({x:0, y:0}, {x:3, y:0}, {x:0, y:3}) |
rectangle |
draw rectangle | draw rectangle({x:0, y:0, w:3, h:3}) |
circle |
draw circle | draw circle({x:0, y:0}, 3) |
point |
draw point | draw point({x:1, y:1}) |
use "move" command
move(1, {x:1, y:1})The range where x changes is definable specifying it.
set xrange = [-5:10]The range of y axis can be specified.
set yrange = [-5:10]The title can be set to the made graph.
set title = ２次関数のグラフ
