Ticks values don't display well

[jeanmile]

When Y axis values is upper than 4 numbers (1000, 2000, etc...), the value is truncated.

Maybe you can use this fast fix is format Y value (line 418 on chart.js) and add tickFormat function :

var yAxis = d3.svg.axis().scale(y).orient(orient)
  .tickFormat(function(d) { return d; });
