Description:

Qtiplot is a fully fledged plotting software similar to the OriginLab Origin software (See http://www.originlab.com for more information 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:
* Cross platform: works natively on Windows, Mac OS X and Linux/Unix
systems
* Fully Python scriptable
* OpenGL based 3D plotting
* Publication quality plots and easy export to various image formats
(EMF, EPS, PS, PDF, SVG, BMP, JPG, PNG, TIFF, etc ...)
* Easy integration with LaTeX typesetting system
* Powerful and versatile spreadsheets with column-logic calculations
and easy import/export of multiple files
* One-click access to extensive built-in data analysis routines
* Advanced statistical analysis: Student's t-Test, ANOVA, chi-square
test for variance, normality test (Shapiro-Wilk)
* Linear and nonlinear curve fitting with weighting and estimation
of statistical errors of the fit-parameters
* Multi-peak fitting
* Image analysis tools
* Templates support: all settings for plots, tables and matrices can
be saved and restored later on for a fast editing process
* Project files based on folders, a powerful project explorer with
built-in drag and drop and searching facilities
* Full import of Excel workbooks and Open Document Format
spreadsheets, dBase, SQLite and Microsoft Access databases

5 Use it in lieu of Sigmaplot, mostly for proper and flexible probability scaling. Program is much more powerful! Registration terms are reasonable and the author is also very responsive.

4 I wasn't able to get Scidavis, so I had no choice. It's similar but you have to get used to.

4 Program is great. It can close up on it own from time to time, but its data manipulation abilites are great. Good for Masters.

4 I like it although there could be some universal format to be portable between origin and other software, origin is in heavy use at universities

5 Qtiplot is pretty much essential for any scientist, or anyone who does any sort of graphing. It is simply amazing and creates publication quality graphs.

4 It's a great free replacement for origin. Stable and fast, it is definitely a useful piece of software. However, conversion of origin files (*.opj format) usually does not work. Also 3D plotting is a bit rough.
