PSI-Plot 8.11a

PSI-Plot software will bring new ease and flexibility to technical plotting and data analysis.
It has a powerful scientific spreadsheet for data analysis; and an object-oriented on screen graphics editor that makes it easy to design and modify graphs. The powerful features combine with the intuitive and user friendly interface have made PSI-Plot one of the most popular data analysis and graphing software. With the newest version 8.1, PSI-Plot is definitely the most advanced yet easy-to use numerical tool for todays scientists and engineers.
Main features:

- New methods for nonlinear curve fitting: simplex method and Powell method.
- With the new programs, you can directly export your plots in the PDF file with a few clicks of your mouse.
- Improved multiple levels data sorting for both balanced and unbalanced data.
- Enhanced mathematical transformation with references to column and cell indices.
- New and enriched data-displaying formats.
- Importing data directly from the Wave format files.
- New data sheet editing capabilities: filling missing cells with linear or spline interpolated data, inserting data block, and improved editing undo.
- New document format control allows you to set the page mode, margin sizes, and many other options such as data title, time stamp, page count, etc.
