Known as the ‘Scientific Graphing Standard’, SigmaPlot 15 is the easy-to-use scientific graphing and
statistical data analysis software package for scientists and engineers who need to create exact, publicationquality
graphs that best communicates their research results for presentations, technical publications or the
web. With advanced curve fitting, a vector-based programming language, macro capability and over 50
frequently use statistical tests, SigmaPlot has the analytical features necessary to extract the important
information from your research data. Then with over 100 graph types and a user interface which allows
detailed manipulation of every graph object you can create the exact graph to present your results.
SigmaPlot 15 has advisory statistical routines and enhances SigmaPlot into a complete statistical analysis
and technical graphing suite. SigmaPlot’s award-winning interface and intuitive wizard technology guides
users step-by-step through the graph creation and data analysis process. More than 300,000 researchers
have used SigmaPlot because it provides the flexibility to create compelling graphs you simply can't get
from a basic spreadsheet package. Users love the ability to interactively modify any small detail of the final
graph to make it the perfect presentation of their data.
Below are some of the many new features in SigmaPlot Version 14:
New Graph Features
Arrows with solid arrowheads
Added a right mouse menu command for pasting copied graph primitives (arrow, box, etc.) on the page
A common operation on a graph is to zoom in, make a modification and then zoom out. A toggle was added, Ctrl+3, between your current zoom level and 100%.
Data sampling dropdown now shows the maximum number of rows in the column
Mini-toolbars for left mouse selection may be turned off
An Anti-aliasing button has been added to the Graph Page Tab, Format Group
Improved user interface for the Color Schemes dialog
The “Each Curve” option is automatically turned on when performing a linear regression on one plot
Additional Plot Regression Statistics
Improved access to result graphs following statistical analysis – obtained by right clicking either a statistical report or another result graph
The scatter matrix graph, used to display results of some statistical tests such as correlation, has increased support from 10 variables previously up to 40 variables
Graph Properties can now be obtained by right clicking a graph or plot
Renamed the Linear Regression command in the Graph Analysis group of the Analysis tab to Plot Regression
Text and special symbols options are now shown directly on the symbols dialog
The Graph Additions Group Name has been changed to Manage Plots

New Analysis Features
The One-Way Frequency Tables method has been added
The unpaired (aka 2-independent samples) t-test has been enhanced to provide options to test the equality of the populations means of the two groups without assuming equal variances (Welch’s t-test)
Ctrl-A now selects all program lines in user defined transforms
More nonlinear regression application examples have been added that can now be accessed from the Help menu
Improvements to the transforms examples that can now be accessed from the Help menu
