Using the Graph class

SinusGraph.java

public static void main(String args[]) { char[][] canvas = new char[24][60]; Graph graph = new Graph(canvas); Function sin = new Function(); graph.clear(); graph.setPen('+'); graph.setRangeX(-Math.PI, Math.PI); graph.setRangeY(-1, 1); graph.draw(sin); System.out.print(graph); }

Firstly, we construct an array of 24 arrays that consists of 60 char each.

Then we pass it to the constructor of Graph. All subsequent operations on graph apply on this canvas.

Until now, all characters of the two-dimensional array have the value '\0'. By using graph.clear() we replace them all by spaces.

graph.setPen allows to set the character that will be used later to mark that cell of the two-dimensional array a function result was mapped to.

Then we select the ranges for the x and y coordinates using the methods setRangeX and setRangeY.

Finally, we draw it and print the result.

	Then we pass it to the constructor of `Graph`. All subsequent operations on `graph` apply on this canvas.
