Veusz 1.13 ---------- Velvet Ember Under Sky Zenith ----------------------------- http://home.gna.org/veusz/ Copyright (C) 2003-2011 Jeremy Sanders <jeremy@jeremysanders.net> and contributors. Licenced under the GPL (version 2 or greater). Veusz is a Qt4 based 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/SVG 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. Data can be captured from external sources such as internet sockets or other programs. Changes in 1.13: * Graphs are rendered in separate threads for speed and a responsive user interface * A changed Graph is rendered immediately on document modification, improving latency * A new ternary plot widget is included * Size of pages can be modified individually in a document * Binary data import added * NPY/NPZ numpy data import added * Axis and tick labels on axes can be rotated at 45 deg intervals * Labels can be plotted next to points on non-orthogonal plots * Add an option for DPI of output EPS and PDF files Minor improvements: * Import dialog detects filename extension to show correct tab * Polygon fill mode for non orthogonal plotting * --plugin command line option added, for loading and testing plugins * Plugin for swapping two colors in a plot * Dataset navigator is moved to right of window by default * Mac OS X binary release updated to Python 2.7.2 * Import plugins can say which file extensions they support * Import plugins can be "promoted" to their own tab on the import dialog * ForceUpdate command added to embedding API, to force an update of the displayed plot (useful if SetUpdateInterval is set to 0) Bugs fixed: * Images plotted when axes are inverted are inverted too * Fixed crash when selecting datasets for plotting in the popup menu * Picker crashes with a constant function * 2D dataset creation using expressions fixed Features of package: * X-Y plots (with errorbars) * Line and function plots * Contour plots * Images (with colour mappings and colorbars) * Stepped plots (for histograms) * Bar graphs * Vector field plots * Box plots * Polar plots * Plotting dates * 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/EMF export * Scripting interface * Dataset creation/manipulation * Embed Veusz within other programs * Text, CSV, FITS and user-plugin importing * Data can be captured from external sources * User defined functions, constants and can import external Python functions * Plugin interface to allow user to write or load code to - import data using new formats - make new datasets, optionally linked to existing datasets - arbitrarily manipulate the document * Data picker Requirements for source install: 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 pyemf >= 2.0.0 (optional for EMF export) http://pyemf.sourceforge.net/ PyMinuit >= 1.1.2 (optional improved fitting) http://code.google.com/p/pyminuit/ For EMF and better SVG export, PyQt >= 4.6 or better is required, to fix a bug in the C++ wrapping For documentation on using Veusz, see the "Documents" directory. The manual is in PDF, HTML and text format (generated from docbook). The examples are also useful documentation. Please also see and contribute to the Veusz wiki: http://barmag.net/veusz-wiki/ Issues with the current version: * Some recent versions of PyQt/SIP will causes crashes when exporting SVG files. Update to 4.7.4 (if released) or a recent snapshot to solve this problem. If you enjoy using Veusz, we would love to hear from you.
