Changing the starting day of the week in the calendar's chart.

[Adolfo Mallenco Pérez]

Hi!

I've noticed that in the Calendar Chart Overview page shows that it is possible to change the starting day of the week:

But I've been not able to get it working. Any indication would be truly appreciated.

I'm also trying to get a .png URI from this kind of chart, but it doesn't work. Is it going to be included in future versions?
