Description

Plotting, nonlinear regression, and curve fitting. Support for Python and LaTeX. Covering all needs of scientists, engineers, and students.

pro Fit is used for efficiently processing data and mathematical functions, evaluating experiments and measurements, and producing publication-ready graphs and drawings. It has an interacting interface that supports directly editing all settings via direct point-and-click.

pro Fit provides a bunch of algorithms for nonlinear regression and curve fitting, the pre-eminent method to check if data is compatible with a theoretical model and to extract information from measurements.

Data is imported into dedicated data windows that support a number of data-transformation options and can be directly accessed from user scripts. A special preview window allows immediate visualization of data and functions, providing an easy way to rapidly visualize how a function changes when anyone of its parameters are modified. Powerful nonlinear regression and curve fitting algorithms are available to identify the parameter values that best describe observations. Dragging function curves to match data in the dedicated preview window is a direct graphical way to identify optimum initial parameter values for subsequent curve fitting.

All graphs and plots are automatically embedded into a full-featured drawing editor that support text and vector graphics with a number of predefined shapes and drawing tools. Any photo, picture, or pdf figure can be imported into a drawing, and equations or other pieces of text can also be written in LaTeX. In this way lots of useful information can be quickly and flexibly added added to the graphs produced from data and functions, which themselves can be easily edited by point and click. The resulting drawings are publication-quality and can be exported as high quality PDF or in a number of other formats.

pro Fit fully supports Python 3 for defining any kind of mathematical function, in addition to a simpler pascal-like language. Any Python function can be immediately visualized in pro Fit's preview window or used for curve-fitting, plotting, or other types of analysis. pro Fit is also scriptable in Pascal, Python, and Apple Script, so that repetitive tasks can be automated.
