SigmaPlot 9 is compatible with SigmaStat 3.1, the guided statistics package, allowing researchers to access frequently used statistical procedures directly from the statistics menu. Category data format options in the Graph Wizard enable users to show differences among groups in their data, or to visualize group effects in multiple comparison charts. Further enhancements include improved histograms for distribution visualization with automatic binning and added symbol types, which will allow users to differentiate multiple groups. Export options, such as PDF for graphs and reports, and HTML for reports, will enable researchers to share their results with colleagues. ODBC-compliant data import and a large number of data worksheet improvements, as well as the new browser-style Notebook Organizer, will ease data entry and navigation as well as notebook control.
