What's New in This Release: [ read full changelog ]

· The RGraph text function has been rewritten
· A drawing API text object has been added making it very easy to add text to your charts which supports events and/or tooltips
· The scale generation function has been rewritten. You won't notice unless you use exponentials - but it's faster and allows for any number of Y labels
· The dynamic scrolling example has been optimised for speed by using local variables. Local variables are the fastest type so you should use them where possible
· Added new properties to the Radar chart: chart.labels.specific, chart.labels.count, chart.labels.axes.bold, chart.labels.axes.bold.zero, chart.labels.axes.boxed, chart.labels.axes.boxed.zero
· The default Pie chart colors have been updated to use gradients
· Set methods can now be chained.
