QtiPlot

QtiPlot

QtiPlot is a fully fledged plotting software similar to the OriginLab Origin, SigmaPlot and Igor Pro.

It can make two and three dimensional plots of publication quality, both from datasets and functions. It can also perform non-linear fitting and multi-peak fitting.

QtiPlot can be successfully used for teaching as well as for complex data analysis and visualisation and is being used in companies, universities and reseach institutes all over the world.

 QtiPlot 0.9.8.9
