API

• Create the graph

  const ctx= canvas.getContext('2d');

  const graph= new Graph({
    context: ctx,
    labels: {
      x: 'foo',
      y: 'bar'
    },
    dimens: {
      width: $canvas.width,
      height: $canvas.height,
    }
  });

• Set the axes for the graph(This will also determine the scale for the graph)

  graph
    .setAxisX([-100, 100])
    .setAxisY([-100, 100]);

• Plot a point on the graph

  graph.plot(x, y);

• Plot a line

  • Standard form

      graph.plotLine({ 'standard': { m: 1, c: 20 }});

  • 2 Point form

      graph.plotLine({ '2 points': [ [ 0, 0 ], [ 2, 1 ] ]});

• Show the graph

  graph.show();
