How do you make the x and y scale equal

[whimsica]

Great Library.
I would like to use this for some science examples but I need to find a way for the x scale to be equal to the y scale. Is there a way to do that?

Also in the documentation to be consistent with the examples
new Chart(ctx).Scatter(data, options);
should be changed to
var mychart=new Chart(ctx).Scatter(data, options);
So the other examples like
myChart.datasets[0].addPoint(5, 7);
will work.
