Extrema, originally developed in the fields of nuclear and particle physics, is a powerful visualization and data analysis tool that enables researchers to quickly distill their large, complex data sets into meaningful information. Its flexibility, sophistication, and power allow you to easily develop your own commands and create highly customized graphs.

Release Notes: The cursor is now positioned at the end of the command line on a command line recall with the up/down arrow keys. Initial indexing for linear interpolation was off by one causing incorrect results in some cases. This is fixed. You can import an image using the "import a drawing" button or the "File->Import" menu item on the Visualization Window, then click the "Digitize" button on the Import Window to be able to digitize coordinates from the image and store the x-y values in vectors.
Release Notes: The REPLOT command was failing for some cases of XLOGBASE or YLOGBASE > 1. The GRAPH command was failing if autoscaling was on and a linear axis was drawn first, with a large maximum value, and then the logbase was set > 1 and the GRAPH drawn again. Setting the virtual min/max was not working properly when the number of large increments was set to zero. The font names used in PostScript output have been changed to get better results.
Release Notes: The FIT command was failing when the fit expression was an evaluable text string, e.g., FIT y=EVALUATE(f) or FIT y=1*f, where f is a text string. This has been fixed.
Release Notes: Several source files were modified to accommodate gcc v4.3, which "cleaned up" some header dependencies.
Release Notes: More polar plot characteristics were added: POLARAXISANGLE, POLARAXISLINEWIDTH, POLARCLOCKWISE, and POLARCOMPASSLABELS. The GRAPH\POLAR and GRAPH\RADAR commands were modified. GRAPH\RADAR draws a polar plot with POLARAXISANGLE set to 90, POLARCLOCKWISE set to 1, and POLARCOMPASSLABELS set to 1. The help files were updated.
