Known Bugs
----------
- dynamicDisplay not working on IOS 5
- If the first label is long, it can be truncated

	    => "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 : [
