Veusz 1.21 ---------- http://home.gna.org/veusz/ Veusz is a scientific plotting package. It is designed to produce publication-ready Postscript, PDF or SVG output. Graphs are built-up by combining plotting widgets. The user interface aims to be simple, consistent and powerful. Veusz provides GUI, Python module, command line, scripting, DBUS and SAMP interfaces 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 1.21: * Add HDF5 saved document format * Add filled curve error bar style * Add fill left/right options for point plotter * Add filetype filters to import dialog file browser dialog * In file completer in import dialog, use selected tab as filter * Move code to use PyQt new style signals * Add a master color setting for xy point and nonorthpoint plot * Line labelling algorithm much improved in contour plots, which rotates text to match line angle and avoids label overlaps * More accurate axis tick label bounding boxes, allowing rotated labels to be placed close together * Add reflection and rotation options to vector field widget * Switch to scientific notation earlier when showing float settings Bug fixes: * Direction combo did not work in import dialog * Saving text datasets did not work in Python3 * Fix partial dataset evaluation issue when loading documents * 2D non-regular pixel spaced images give error if clipped in y * Handle Unicode quoted characters in simple text data files * xcent/ycent in Dataset2D import plugins were ignored * promote_tab broken for import plugins * Full screen view when all pages are deleted * Crash with empty dataset and boxplot widget * Fix copy and paste of datasets * Python 3 resizing axis bug * Crash if picking/zooming on document with no pages * Crash if reediting histogram dataset with blank output entry * Use end of text formatting string beyond format specifier * When writing SVG text as text, use xml:space="preserve" to avoid missing whitespace * Embedding socket issue on Python 3.4+ Features of package: Plotting features: * 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 * Ternary plots * Plotting dates * Fitting functions to data * Stacked plots and arrays of plots * Nested plots * Plot keys * Plot labels * Shapes and arrows on plots * LaTeX-like formatting for text * Multiple axes * Axes with steps in axis scale (broken axes) * Axis scales using functional forms * Plotting functions of datasets Input and output: * EPS/PDF/PNG/SVG/EMF export * Dataset creation/manipulation * Embed Veusz within other programs * Text, HDF5, CSV, FITS, NPY/NPZ, QDP, binary and user-plugin importing * Data can be captured from external sources Extending: * Use as a Python module * 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 * Scripting interface * Control with DBUS and SAMP Other features: * Data picker * Interactive tutorial * Multithreaded rendering Requirements for source install: Python 2.x (2.6 or greater required) or 3.x (3.3 or greater required) http://www.python.org/ Qt >= 4.6 (free edition) http://www.trolltech.com/products/qt/ PyQt >= 4.5 (SIP is required to be installed first) http://www.riverbankcomputing.co.uk/software/pyqt/ http://www.riverbankcomputing.co.uk/software/sip/ numpy >= 1.0 http://numpy.scipy.org/ Optional requirements: h5py (optional for HDF5 support) http://www.h5py.org/ astropy >= 0.2 or PyFITS >= 1.1 (optional for FITS import) http://www.stsci.edu/resources/software_hardware/pyfits http://www.astropy.org/ 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/ dbus-python, for dbus interface http://dbus.freedesktop.org/doc/dbus-python/ astropy (optional for VO table import) http://www.astropy.org/ SAMPy (optional for SAMP support) http://pypi.python.org/pypi/sampy/ Veusz is Copyright (C) 2003-2014 Jeremy Sanders <jeremy@jeremysanders.net> and contributors.
