Why does Portrait 4 have such a short learning curve?
Portrait 4 provides four critical features that significantly shorten the steep learning curve associated with traditional graphing calculators.
1. The Power and familiarity of Windows
Portrait 4's interface is Windows-based. Everything is menu-driven. Your previous knowledge of computers provides you with most of what you need to know to start using Portrait 4.
Portrait 4's interface is also consistent across the different versions we provide. Somebody using the Windows version on a desktop can instantly switch to our Windows Mobile, Windows CE, Mac, Linux versions of the software.
* Note: Screen shots are taken on Windows, however Portrait 4's functionality is consistent across all of our supported platforms: Windows, Mac, Linux and Windows Mobile.

2. Built-in templates for every function
Portrait 4's function templates have clearly labeled boxes for each of the pieces of data that need to be entered. You don't have to worry about committing long keying sequences to memory or entering data in a specified order.

4. Sample Data
Portrait 4 provides model examples with sample data for every graph and function. Here is one of the examples provided for a Pie Graph. The Sample Menu is located in the Edit Menu. Tapping one of the three samples generates a set of labels and data you can immediately graph.

These four features are like a daily tutor that is always available to let you know how Portrait 4 works. You don't need to spend hours poring over a 500 to 600 page user's guide trying to figure out how to make your calculator do the things you need it to do.
This ensures that your learning curve stays flat every time you work with a new graph or function using Portrait 4.
