What is SigmaPlot?

SigmaPlot is a scientific data analysis and graphing software that allows users to visualize and analyze their data. It provides a range of graphing options, statistical analyses, and customization tools to create high-quality graphs and charts for presentations and publications, and is widely used in scientific research, engineering, and other fields that require data analysis and visualization.

SigmaPlot help researchers visualise their research data and create publication-ready graphs with advisory statistics and graphing capabilities. This means advanced statistical analysis and data visualisation can be done without needing to learn complex syntax or programming. SigmaPlot guides users through every step of the analysis process, performing powerful statistical analysis without you needing to be a statistical expert.

A few of the ways SigmaPlot can enhance your research:

  • Graphing and Visualisation
    SigmaPlot makes it easy to create and customize a wide range of graphs and plots, including scatterplots, line graphs, bar charts, and more. With its intuitive interface and powerful customization tools, SigmaPlot allows you to create publication-quality visuals that effectively communicate your findings.
  • Statistical Analysis
    With SigmaPlot, you can perform a wide range of statistical analyses, from basic descriptive statistics to advanced multivariate analyses. SigmaPlot includes a comprehensive library of statistical tests and methods, making it easy to identify patterns and relationships in your data.
  • Data Management
    SigmaPlot provides a suite of tools for managing your data, including import and export, cleaning and transformation, and filtering and sorting. This makes it easy to prepare your data for analysis and ensure that your results are accurate and reliable.
  • Presentation
    SigmaPlot allows you to easily export your graphs and analyses to a variety of formats, including PowerPoint, Word, PDF, EPS and TIFF. This makes it easy to incorporate your findings into presentations, papers, and reports.

SigmaPlot has a user-friendly interface and is easy to learn

SigmaPlot includes over 100 2D and 3D graph types and templates, 50 statistical methods, and seamless integration with Microsoft Office. The user interface is familiar enough for experienced users but easy enough for novice users to understand. And with step-by-step wizards available as a resource for novice analysts, getting things done with SigmaPlot couldn’t be simpler.

Whether you’re looking to visualise your data quickly, create professional graphs, or advanced Statistical reports, SigmaPlot has you covered. Its step-by-step wizards make it easy for even non-technical users to create impressive results.

With the new Graph Properties user interface, you can select the property category in the tree on the left and then change properties on the right. The change is immediately graphed, and if you move your cursor off the panel, it becomes transparent, and you can see the effect of your changes without leaving the panel.

You have the flexibility to customize every detail of your graph. You can add axis breaks, standard or asymmetric error bars and symbols, and change colours, fonts, and line thickness. Double-click on any graph element to launch the Graph Properties dialogue box.

Modify your graph, chart or diagram further by pasting an equation, symbol, map, picture, illustration or another image into your presentation. And select anti-aliasing to display jaggy-free smooth lines that can be used in your PowerPoint® presentations.

Statistics and Data Analysis without the learning curve

You get all the fundamental tools you need to analyze your data, from basic statistics to advanced mathematical calculations and statistical methods. Click the Statistics button to instantly generate summary statistics, including 95% and 99% confidence intervals. Run t-tests, linear regressions, non-linear regressions and ANOVA with ease. You can fit a curve, plot a function, and get results reports in seconds. Use built-in transforms to massage your data and create a unique chart, diagram or figure. With SigmaPlot – it’s all so simple!

Use the Regression Wizard to fit data easily and accurately

Fitting your data is easy with the Regression Wizard. The Regression Wizard automatically determines your initial parameters, writes a statistical report, saves your equation to your SigmaPlot Notebook, and adds your results to existing graphs or creates a new one!

The Regression Wizard accurately fits nearly any equation – piecewise continuous, multifunctional, weighted, Boolean functions and more – up to 10 variables and 25 parameters. You can even add your curve fit equations and add them to the Regression Wizard.

Use the Dynamic Curve Fitter to analyse your data

The Dynamic Curve Fitter performs 200 or more curve fits using your equation and data from optimally different initial starting values. The results are ranked by the goodness of fit so that you can check the top-ranked results against the result you obtained from the Regression Wizard. There is always a concern that the correct solution has not been found. Dynamic fitting minimizes this concern. It is encouraged before publishing results, particularly if a complicated equation is used.


New features in Sigmaplot 15

New graph features and possibilities, new and improved worksheet features, and new and improved statistics and analysis features.

Heat Maps (New graph type macro)

Heat maps assist in visualizing variations in the density of values in the data table. Put another way, heat maps are used to identify clusters of data. The primary benefit of heat maps is that they make complicated data simpler to understand than the output of many other graphical or numerical techniques. One of the original and frequently used applications of heat maps is to examine population density in a city or region.
