Qtiplot is a fully fledged plotting software similar to the OriginLab Origin software (See http://www.originlab.com for more informations about Origin).

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

Some Features:
* 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.
