Useful Free Graphing App for the iPad: DataAnalysis
By Graham K. Rogers
I do understand more simple forms of data use, particularly (for example) pie charts and the basic X, Y graph which is one of the easiest data displays to grasp with its ups and downs.
As the iPad has become a tool for calculating, producing information and displaying it, either by holding the screen under someone's nose, or by displaying on a larger screen, the idea of a simple tool for graphing data is rather appealing.
The developer site itself is worth a visit as there are several items accessible that will guide users through the more complex operations possible. Indeed, there is so much useful information, much of it cross-linked with other pages, that my usual explanation of how I work through an app are pretty much redundant.
Far simpler was copying the text into an email, then using copy and paste on the iPad when the message arrived. I was able to graph the data (not that it meant much in the rough and ready form I had it) with a simple button press.
The graphs may be adjusted in terms of the displays with an easy to use scroll-wheel method of changing data points and lines (e.g. dotted and solid, thick or thin). Graphs so produced may be exported in a number of formats including PDF and PNG. The app integrates with DropBox and data can be transferred via this service in a number of formats, including PDF, text (txt) and PNG files.
For a straight forward graphing app that is easy to use and produces quite satisfying results, the free DataAnalysis app is well worth a look.
