# 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 is the function of the graph, and the draw command draws the graph from the coordinate of to .

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));

This graph, like with any draw command, can have several attributes fixed to it, such as color:

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.
