TheBarGraph offers you the ability to generate bar charts and send them over email. And the iPad version makes it even easier than the iPhone one.
Bar graphs are useful for comparing a set of numerical quantities at a glance.
The iPad image below shows the population growth rate (%) in year 2009 for 5 countries.
The bars representing population growth are sorted by value, with the highest values at the top.
It is also possible to sort them by the bar names.
The graph can be emailed by tapping the Send button. And it is possible to magnify the image to be sent from 0.1 to 5.0 times.
The iPad image above is live. You can click with your mouse on the buttons to navigate from one view to another, like on a real iPad.
