Today I released v 1.3.1 of all charts. The main new feature is that now you can print charts with JavaScript. Check js_example.html to see how it works.
There are two functions for printing:
flashMovie.print();
and
flashMovie.printAsBitmap();
In most cases the first one, print() function will produce a better result. However if you have rotated by 90 degrees labels, transparent objects or background images, it might be better to use the second function.
