Veusz 1.26.1
------------
https://veusz.github.io

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 1.26.1:
 * Change homepage in program to new site https://veusz.github.io/
 * Change new version checking to use veusz.github.io

Changes in 1.26:
 * Add color themes and automatic coloring of widgets
 * Custom color definitions
 * Improved custom definition dialog box
 * Fix loading translator via command line
 * Show horizontal error lines/fills in key
 * Use iMinuit if available for fitting
 * Fix for dataset plugins returning nD datasets
 * Add editable automatic axis range, including support for shrinking
   range (-X%), percentage ranges (X-Y%) and limits (<X% and >Y%)
 * Fix for key if invalid dataset
 * For log scaling on image widget, show invalid values as being transparent

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

  * 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 filtering and manipulation
  * Data picker
  * Interactive tutorial
  * Multithreaded rendering
