The DataGraph help site can be accessed through the help menu in DataGraph, as well as in a standard web browser. The help is stored on-line, so you need to be connected to the internet to view this help.

DataGraph is designed to be a structured drawing program focused on drawing x-y data (
line and scatter), analytic functions and bar graphs. It also contains a number of commonly used analysis tools, such as function fit, histogram and box plot. DataGraph uses smart defaults and automatic rules to create clean looking graphs, but you can customize and overwrite those rules. The user interface is explained further on a separate page.

Easy to compute
function fits and draw analytical functions.

Expression - To map numerical values using expressions.
Get full control over the
behavior of axis
Splitting the axis and drawing
multiple x/y axis is easy.
Every numerical field accepts an
expression
Every text label is
tokenized and can change dynamically.
Can use
special characters (e.g. greek) mathematical functions and style changes.
Statistical tools such as
histograms and box plots.

For further exploration:
Define
constants that you can use in numerical fields.
Use the
Loupe tool to zoom in on a detail.
Define
additional axis, allowing you to change units and more control over tick marks.

For the programming types:
Can use DataGraph from the
command line to create graphics and movies.
Can use DataGraph
inside Automator.
Can use the
underlying drawing engine in your own Cocoa applications.
