Veusz 3.1 --------- https://veusz.github.io Veusz is a 2D and 3D scientific plotting package. It is designed to produce publication-ready 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 3.1: Improvements: * Do not print or export hidden pages * Allow expressions in dataset of contour widget * Allow widgets to be excluded in key (thanks to Alexander Book) * Make bezier line better fit data * Switch linux binary from x86 -> x86-64 for better compatibility Bug fixes: * Compilation fix for PyQt>=5.12 (thanks to Dimitry Shachnev) * Ensure fit settings are sorted in output file * Fix crash in contour labelling * Fix 3D axis crash bug * Fix problem with broken axis with null-sized regions * Fix issue with 0-sized images in image widget * Fix function widget crash with certain plotting range * Fix for axis crash with large magnitude ranges * Fix CSV importing issues for 2D and ND data * Fix zero division error in 2D import * Fix crash on importing HDF5 files with variable length text * Catch issue with zero range axes * Fix crash is using set in dataset expression * Fix crash when moving line coordinates * Remove deprecation warnings when compiling with recent Qt versions Changes in 3.0.1: * Change in build system to use qmake to find Qt locations. This is to fix the build inside Anaconda. Also Qt and sip parameters can now be given as environment variables. * Fix problem when picking points with too many non-finite values * Change default SVG export DPI to 96 to match inkscape and provide option in dialog to choose export DPI * Allow %PAGE% and %PAGENAME% in export filename for single page output * Fix failing fitting due to iminuit differences * Fix crash if both ends of part of broken axis widget are the same for EMF exporting * Update to Qt 5.11.1 and update PyQt and sip in Windows binary * Build Mac and Linux binaries with EMF export Changes in 3.0: * New 3D support for plotting points, functions, surfaces and volumes * Add --export-option parameter for command line exporting control * Add templates in preferences for exported file names, add %PAGE00% and %PAGE000% options for zero-prefixed page numbers, and change %PAGENUM% to %PAGE% * In export dialog allow user to specify arbitrary pages to export * Change miter limit for lines, which fixes some problems when exporting arrow to PDFs * Use flat cap on lines with arrows, to avoid line showing through head * Support datetime64 and string/unicode characters in npy/npz import * Add \hat LaTeX support 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 * 3D point plots * 3D surface plots * 3D function plots * 3D volumetric plots Input and output: * PDF/EPS/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 filtering and manipulation * Data picker * Interactive tutorial * Multithreaded rendering Requirements for source install: Python 2.x (2.7 or greater required) or 3.x (3.3 or greater required) https://www.python.org/ Qt >= 5.5 (free edition) https://www.qt.io/ PyQt >= 5.2 (Qt and SIP is required to be installed first) https://www.riverbankcomputing.co.uk/software/pyqt/ SIP >= 4.15 https://www.riverbankcomputing.co.uk/software/sip/ numpy >= 1.7 http://www.numpy.org/ argparse (for Python 2.6 only) https://pypi.python.org/pypi/argparse Optional requirements: h5py (optional for HDF5 support) http://www.h5py.org/ pyemf >= 2.0.0 (optional for EMF export) http://pyemf.sourceforge.net/ https://github.com/jeremysanders/pyemf (Python 3 port in development) iminuit or PyMinuit >= 1.12 (optional improved fitting) https://github.com/iminuit/iminuit dbus-python, for dbus interface http://dbus.freedesktop.org/doc/dbus-python/ astropy (optional for VO table import and FITS import) http://www.astropy.org/ SAMPy or astropy >= 0.4 (optional for SAMP support) http://pypi.python.org/pypi/sampy/ Ghostscript (for EPS/PS output) https://www.ghostscript.com/ Veusz is Copyright (C) 2003-2018 Jeremy Sanders <jeremy@jeremysanders.net> and contributors.
