# Asymptote: Graphing

Note These example are for the AoPS forums, If you want to use them on your computer, you must "import graph;".

There are two parts to a graph.

The axes' codes:

```Label f;
f.p=fontsize(6);
xaxis(-8,8,Ticks(f, 2.0));
yaxis(-8,8,Ticks(f, 2.0));
```

This means ticks at an interval of 2.0, between -8 and 8 for both the x and y axes.

And the graph code:

```real f(real x)
{
return x^3;
}
draw(graph(f,-2,2));```

The return $x^3$ is the function of the graph, and the draw command draws the graph from the $x$ coordinate of $x = - 2$ to $x = 2$. $[asy] import graph; size(300); Label f; f.p=fontsize(6); xaxis(-8,8,Ticks(f, 2.0)); yaxis(-8,8,Ticks(f, 2.0)); real f(real x) { return x^3; } draw(graph(f,-2,2)); [/asy]$

We can also alter the ticks code. For example, if we want intervals of 2 labeled, then 0.5 in between each one, we can use the following code:

```Label f;
f.p=fontsize(6);
xaxis(-8,8,Ticks(f, 2.0,0.5));
yaxis(-8,8,Ticks(f, 2.0,0.5));
``` $[asy] Label f; f.p=fontsize(6); xaxis(-8,8,Ticks(f, 2.0,0.5)); yaxis(-8,8,Ticks(f, 2.0,0.5)); [/asy]$ This graph, like with any draw command, can have several attributes fixed to it, such as color: $[asy] import graph; size(300); Label f; f.p=fontsize(6); xaxis(-8,8,Ticks(f, 2.0)); yaxis(-8,8,Ticks(f, 2.0)); real f(real x) { return x^3; } draw(graph(f,-2,2),green+linewidth(1)); [/asy]$

```import graph;
size(300);
Label f;
f.p=fontsize(6);
xaxis(-8,8,Ticks(f, 2.0));
yaxis(-8,8,Ticks(f, 2.0));
real f(real x)
{
return x^3;
}
draw(graph(f,-2,2),green+linewidth(1));
```

Remember, you can still draw normal functions, so you can create lines, circles and ellipses.
