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.

Features include:
- 3D Plots
- Publication quality 2D plots: Error Bars, Multilayer Plots,
Bar Plots, Pie Plots, Vector Plots, Contour and Image Plots
- Statistical Plots: Box/Whiskers Diagramms, Histograms
- Easy export of plots to vector formats (EPS, PS, PDF) and
to other various image formats (BMP, JPG, PNG, TIFF)
- Powerful and versatile spreadsheets and calculations in
column-logic
- Easy ASCII-Import/Export of single or multiple files
- Linear
and non-linear curve fitting with weighting and estimation of
statistical errors of the fit-parameters, using Levenberg-Marquardt,
Least-Squares Algorithm or Nelder-Mead simplex minimization algorithm
- Multi-peak fitting with Gaussian and Lorentzian peak
profiles
- Data
analysis: statistics, sorting, FFT, data smoothing (Savitzky-Golay, FFT
smoothing, and moving window average), data filtering (low/high/band
pass and band block filters), convolution/deconvolution, correlation,
interpolation, numerical integration/differentiation
- Matrices optimized for 3D plotting
- Templates
support: all the settings for plots (2D/3D), tables and matrixes can be
saved to ASCII files and restored later on for a fast
editing process
- Project files based on folders, a powerful
project explorer with extensive built-in features: drag and drop,
searching facilities
