Veusz 1.3 --------- Velvet Ember Under Sky Zenith ----------------------------- http://home.gna.org/veusz/ Veusz is Copyright (C) 2003-2009 Jeremy Sanders Licenced under the GPL (version 2 or greater). Veusz is a scientific plotting package. It is written in Python, using PyQt4 for display and user-interfaces, and numpy for handling the numeric data. Veusz is designed to produce publication-ready Postscript/PDF output. The user interface aims to be simple, consistent and powerful. Veusz provides a GUI, command line, embedding and scripting interface (based on Python) to its plotting facilities. It also allows for manipulation and editing of datasets. Changes in 1.3: * Add data capture from sockets, files and external programs * Remembers previous entries in dialog boxes * Add shaded regions or lines error bar style * Plot keys can be dragged around with the mouse * New clearer scalable icons * Now requires Python >= 2.4 * minor changes - Add filename completion in several places - Remember import dialog tab selection - Use font drop-down to select font - Add icons for error bar styles - Error bar code rewritten and simplified - Add import dialog to toolbar * bug fixes: - Fix incorrect "security errors" when loading invalid documents - Fix dragging around of shapes and lines problems - Fix address of FSF in license - Fix appearance of dialog box fonts on some systems - Fix recent files menu - Fix hiding of pages and graphs Features of package: * X-Y plots (with errorbars) * Line and function plots * Contour plots * Images (with colour mappings and colorbars) * Stepped plots (for histograms) * Fitting functions to data * Stacked plots and arrays of plots * Plot keys * Plot labels * Shapes and arrows on plots * LaTeX-like formatting for text * EPS/PDF/PNG/SVG export * Scripting interface * Dataset creation/manipulation * Embed Veusz within other programs * Text, CSV and FITS importing Requirements: Python (2.4 or greater required) http://www.python.org/ Qt >= 4.3 (free edition) http://www.trolltech.com/products/qt/ PyQt >= 4.3 (SIP is required to be installed first) http://www.riverbankcomputing.co.uk/pyqt/ http://www.riverbankcomputing.co.uk/sip/ numpy >= 1.0 http://numpy.scipy.org/ Optional: Microsoft Core Fonts (recommended for nice output) http://corefonts.sourceforge.net/ PyFITS >= 1.1 (optional for FITS import) http://www.stsci.edu/resources/software_hardware/pyfits For documentation on using Veusz, see the "Documents" directory. The manual is in pdf, html and text format (generated from docbook). Issues: * Can be very slow to plot large datasets if antialiasing is enabled. Right click on graph and disable antialias to speed up output. If you enjoy using Veusz, I would love to hear from you.
