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.
