It's nearly a year now since the Google Chart API was launched, and we've got some treats for you to celebrate!

We've added several new options for adding markers to your chart, including financial markers, which lots of you have been asking for!



And you can now use invisible guide data sets to position markers accurately on your chart. Anyone who's got independent data lines on their wishlist - this one is for you!



If you were looking for concentric pie charts, or the ability to control the orientation of your pie chart, you're in luck!





Other new features include
  • Control for axis lines and tick marks
  • Data labels
  • Margin control
  • Automatic spacing for bar charts

You can read more about all of these features, and the updates we've made to the existing features, on the Chart API site.
