As you might have read in the comments, version 1.1 will be released soon! I will submit it to Apple for review in about a week. It will be a very huge update featuring changes in the user interface, some minor changes in the graph and different data sets. I'll post here when it becomes available.
Since the iTunes Store only permits an upload of 5 images, here are some more showing the functionality. The figures are showing 2 different settings on a pie chart, the 2D bar chart as well as the scatter chart. If you have any questions, post a comment!
