SigmaPlot plots a high resolution course
As published in Scientific Computing World, issue 57
SigmaPlot 2001, the latest version of the scientific graphing software from SPSS, enables users to publish graphs and charts as high-resolution, interactive web objects. With this version, users can export graphs as dynamic web objects to be posted on a website or an intranet page instead of GIFs or JPEGs.
SigmaPlot's WebViewer enables anyone - whether or not they have SigmaPlot - to explore the data used to create the graph and to zoom, pan or print the image at full resolution directly from a web browser window. There are also optional security settings.
The WebViewer, a free Internet Explorer plug-in, is automatically downloaded when the browser first encounters a SigmaPlot 2001 graph. If for any reason the Viewer plug-in is not installed, the browser will display a screen resolution JPEG image. SigmaPlot offers numerous scientific options such as automatic error bars, regression lines, confidence intervals, axis breaks, technical axis scales, non-linear curve fitting and a data worksheet for powerful data handling. Add-ons such as the Enzyme Kinetics and Electrophysiology modules provide custom capabilities for specific research applications.
New features in SigmaPlot 2001 include: area plots whereby researchers can shade areas below or between curves, calling attention to regions of particular interest; graph style gallery, allowing users to save templates of their favourite graphs for reuse, saving the time and effort of recreating complex plots; equation solver, to solve equations or functions containing a single independent variable and any number of parameters; and true colour EPS export, whereby images can be exported as full colour vector EPS files, the preferred format for illustration and page layout programs. Another new export option is the TIFF CMYK compressed format.
