  10 reviews

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
* 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

This software is fantastic. I have been using it in my work for 5 years now. You should really consider purchasing the last version and the maintenance contract. It's worth it. The author is very responsive.

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.

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

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

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

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.

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.
