- display the legend on other places (center, bottom or top on the left/right of the graph;
center, right, left over/under the graph).
- non evolutive animation in Pie/Doughnut (https://github.com/nnnick/Chart.js/issues/357)
- code reduction
- animate Canvas when mouse is over a piece of graph (like in http://zurb.com/playground/pizza-pie-charts)
- dynamicDisplay defines a canvas.id when not defined; Avoid defining a canvas.id (issue 35)
- Different units for Y-axes on left and right (issue #41)

Known Bugs
----------
- dynamicDisplay not working on IOS 5
- Pie not working on some devices
- If the first label is long, it can be truncated
In "sample.html", if you put :
var mydata1 = {
labels : ["January this is a very long label","February","March","April","May","June","July"],
=> "January this is a very long label" will be truncated (outside of the graph area)
- not enough labels on the Y-Axis (with logarithmic options)
var negdata1 = {
labels : ["January","February","March","April","May","June","July"],
datasets : [
{
fillColor : "rgba(220,220,220,0.5)",
strokeColor : "rgba(220,220,220,1)",
pointColor : "rgba(220,220,220,1)",
pointStrokeColor : "#fff",
data : [-100,-50,-90,-81,-56,-25,-100],
title : "First data"
},
{
fillColor : "rgba(151,187,205,0.5)",
strokeColor : "rgba(151,187,205,1)",
pointColor : "rgba(151,187,205,1)",
pointStrokeColor : "#fff",
data : [-28,-48,-40,-19,-96,-27,-100],
