Veusz is a scientific plotting package, designed to create publication-ready Postscript, PDF or SVG output. It can create line graphs, XY plots, histograms, shapes, images, ternary plots, polar plots, box plots, vector field plots and contour plots. It features GUI, command-line, and scripting interfaces. Graphs are constructed from components, allowing complex layouts to be designed.


* Text labels can now include Python expressions inside %{{ }}%
* Added built-in functions DATE([fmt]), TIME([fmt]), FILENAME() and BASENAME() when evaluating expressions, which are useful when used in labels
* Added Python dictionary ENVIRON when evaluating expressions, to obtain values from environment variables
* Added DATA(name, [part]) function to expression environment for accessing values from datasets, useful for function evaluation or labels
* Added SETTING(path) function for expression evaluation to obtain values of settings
* Added ESCAPE(text) function to environment, which allows LaTeX special characters to be displayed in labels
* Add fractions and percentages units to polar plot
* Allow number of spokes to be varied in polar plot
* Widgets can be clicked holding down shift or ctrl, to add or toggle their selection
* Add K. Moreland's cool-warm colormap (thanks to S. Richardson)
* Added further green-map, blue-darkred, blue-darkorange, brown-blue and blue-orange colormaps from Oregon geography dept.
* Add logarithm and exponential dataset plugins
* Add Wipe() command to embedding interface to clear document
* Add File->Reload menu option to reload from saved document
* Add tooltip to items in FieldWidget showing widget path

Bux fixes:
* Fix transparency with bar plot
* Use getcwdu() for python2 to avoid bugs combining paths
* Handle inf/nan when converting to human readable form in plots
* Fix CreateHistogram on command line without binparams parameter
* Handle empty 2D dataset import with grid at edge enabled
* Do not allow error bars on imported CSV non-numeric data
* Handle missing argument in \size
* For data edit dialog, allow 1D dataset to replace 2D dataset
* Crash if zoom to be height when height is zero
* Fix problem with 2D import if error message is in unicode
* With axis-function widget catch result if greater than 1 dimension
* Fix cloning for datasets with / in name
* Fix crash in embedding if plot window closed while rendering in progress

I really like your app. The usability for me is much better than with other commercial competitors. Thank you!

However, I do have some trouble, when I try to plot data with >100000 data points (no you cannot compress that). Then the performanc is quite slow. I think this is due to the usage of python as a interpreter language, right? Or can I improve something else on my machine?

Thanks again!

You can turn off antialiasing by right clicking on the plot and deselecting it. This helps speed up things a lot!

Veusz 1.8+ is much faster for plotting large datasets as the inner plotting loops have been rewritten in C++.

This app is great. The quality results are gorgeous and ready for professional journal. I've tried other programs and Veus is better.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
