QtiPlot

QtiPlot is a top-tier software designed for two- and three-dimensional graphical presentation of data sets and thorough data analysis. Rooted in the Education category, specifically under Science Tools, this program has made a strong reputation for itself within the scientific community. The latest version, 1.1.7, brings enhanced features that professionals appreciate.

Unlike many similar tools, QtiPlot is cross-platform, meaning it works natively on Windows, Mac OS X, and Linux/Unix systems. Notably, it is fully Python scriptable, which adds incredible flexibility for custom functionalities. The OpenGL based 3D plotting ensures users can produce high-quality, publication-ready plots, with easy export options to various image formats such as EMF, EPS, PS, PDF, SVG, BMP, JPG, PNG, and TIFF.

Developed by Ion Vasilief, the program supports a wide range of Windows OS versions, from Windows 2000, XP, Vista, 7, 8, 10, and 11, ensuring compatibility with both older and newer systems. QtiPlot also integrates seamlessly with the LaTeX typesetting system, which is a major plus for those in academia.

Users can expect powerful and versatile spreadsheets with column-logic calculations, allowing for easy import/export of multiple files. The program also boasts extensive built-in data analysis routines accessible with a single click. Advanced statistical analysis capabilities, such as the Student's t-Test, ANOVA, chi-square test for variance, and normality test (Shapiro-Wilk), make it a robust tool for researchers.

The software supports linear and nonlinear curve fitting with weighting and estimation of statistical errors of the fit-parameters, and even multi-peak fitting. Additional image analysis tools and template support allow for efficient repeatability in projects.

QtiPlot also offers project files based on folders, featuring a powerful project explorer with built-in drag and drop and searching capabilities, making it a user-friendly choice. It excels in full import of OriginLab® Origin projects, Excel workbooks, and Open Document Format spreadsheets, adding to its versatility.

For those looking for previous versions, QtiPlot has histories like 0.9, and 0.8, ensuring that users can find and use a version that suits their needs.
