Guppi is a GNOME-based framework for graphing and interactive data analysis.
Guppi is a library that can be used to extend other programs. Your own programs can either link directly to Guppi's shared libraries, or can embed Guppi plots via Bonobo, GNOME's component architecture.
Guppi is still in an early stage of development, and is still missing several important features. We would still like to encourage you to download Guppi and try it out. If you need a fully-functional plotting package right now, you might want to look into some other free plot programs.
Here are some key features of "Guppi":
An Extensible Design: Guppi is designed from the ground up to be easily extensible system. Instead of being a single monolithic program, Guppi consists of a small core system, with all of the interesting functionality residing in modular plug-in extensions. By writing plug-ins, it is possible to add new plot types, data import methods, data processing back-ends and statistical operations.
Modularity For Reuse: All of the interesting functionality in Guppi is broken out into several shared libraries. This allows other programmers to add Guppi's interactive plotting capabilities to their own programs.
Full Scripting Capabilities: Guppi's entire API is available via both Scheme and Python, two widely-known programming languages. Since the graphical toolkit that Guppi is built with can also be accessed via Scheme and Python, this means that Guppi's user interface can be extended in arbitrarily complex ways from user scripts.
GNOME Integration: Guppi is being developed as part of the larger GNOME Project, which is dedicated to creating a totally free, user-friendly computing experience for Unix-like operating systems. Thus Guppi will be a well-integrated with a complete suite of productivity software
Freely available source code: Guppi's full source code is available for you: you are free (and in fact encouraged!) to examine it, modify it, customize it, extend it, and pass copies along to others. The goal of the Guppi Project is to create an open system than can be used by either analysts or academics, and which is both a useful tool and a valuable platform for research.
The following is a list of some of the specific capabilities of Guppi. Guppi is under active development, so expect this list to grow.
Basic statistics on sets of real numbers: mean, standard deviation, min, max, median, quartiles, percentiles, covariance, correlation.
Simple linear regression, with analysis: F, p, t-values of model coefficients.
Support for missing values in data sets.
Transformed views of data sets: square root, square, log, exp, absolute value, standardization, logit.
"Smart" data importer for text files containing delimited data sets.
Basic plot types: scatter plots, line plots, bar charts, pie charts. All plots are fully interactive.
Overlayed regression lines, labeled with model equation.
Scatter plot markers can be colored and sized by data.
Brushing in scatter plots.
Support for logarithmically-scaled axes.
All plots can be printed as Postscript or PCL. They can be sized in real-world units (i.e. 6" x 4") and the printed output exactly matches the on-screen display.
On-screen displays are fully anti-aliased and can be rescaled to any magnification level.
Translated into Danish, French, German, Icelandic, Norwegian, Russian, Swedish and Ukrainian.
