Overview

Veusz 3.3.1

Veusz is a 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.

  • New tools for zooming into plot on click, zooming out, moving plot center and resetting plot axes
  • Double clicking on axis range resets endpoint to Auto
  • Add key entries for histo widget
  • MacOS improvements
    • Big Sur compatibility fix
    • Fix file associations
  • Python 3.10 prerelease fixes

  • New separate lo and hi error bar styles (#428)
  • Use same colour for key title as key text (#414)
  • Add preferences for number of significant figures in picker
  • New colormaps: inferno, magma, moreland, parula, plasma and viridis
  • Add CurrentPath() API command to get current widget path
  • Add dataset operations for reversing and subtracting dataset maximum
  • Now supports building using sip5
  • Bugfix for values in boxplots (#455)
  • Add setting to optionally omit paths in document files

    Hi. I really like Veusz. I am curious about how the smoothing seems to deliver some odd results at times. The attached image shows some lines drawn in Excel (top) and Veusz (bottom). I prefer Veusz over Excel almost always, but I think you can see that the smoothing here is Veusz is delivering some strange results. In particular, the big peak -- the line seems to go backwards, with the x value decreasing near (2015,0.125), which I think would be an arror in most circumstances. I cannot pretend to be able to offer a solution. If there is a sort of 'tension' parameter, that might help? Any advice welcome.

    Both configure and build phases fail with this option:

    Setting the environment variable SIP_DIR also doesn't seem to have any effect.

    How to set the sip dir?

    On FreeBSD the sip directory is /usr/local/share/PyQt5/3.6/sip, and it can't find it by default.

  • Move all hide checkboxes to top

    Move all hide checkboxes to top

    This PR is born out of a personal frustration: I often check the effect of a setting by hiding/unhiding the widget. For this to work effectively, the hide checkbox should always be at the same place and easily reachable. IMHO this best place is at the very top of the settings, but #92 has a different idea (at the bottom – but then you always have to scroll down to the bottom …)

    This PR implements this with the check box(es) always at the top. If the check box should be at the bottom, the method setting.settings.Settings.getNames() should be changed from

        def getNames(self):
        """Return list of names."""
        return self.hideboxnames + self.setnames

    to

        def getNames(self):
        """Return list of names."""
        return self.setnames + self.hideboxnames

    This could be even made a configuration option? But then I am not sure, if the reversal of

       def saveText(self, saveall, rootname = None):

    would still work, if the file is loaded with the checkboxes set to a different position …

  • Feature request: Add more functionality to

    Feature request: Add more functionality to "Zoom into graph"

    Currently, the "Zoom into graph" tool in the main window toolbar does exactly what it says - it lets you zoom into a chosen area in the graph. However, it also does exclusively what it says, meaning that once you've zoomed in you lack any interactive tools to pan the graph, zoom out, or reset to previous zoom steps. I feel that this is sorely missing.

    Basically, my suggestion is to implement a similar set of tools as we already have for zooming the entire page.

    This behaviors were reproduced multiple OSs (Ubuntu, Windows, and MacOS) and also occurs with self-built program.

    I have found a work around. The files become to work well, by importing modules in each method instead of the global section. (example: https://github.com/korintje/SPAImportPlugin_for_Veusz/blob/main/spa_import_34.py).

    # This will work

from veusz.plugins import ImportPlugin, importpluginregistry

class ImportPluginExample(ImportPlugin):

    def __init__(self):
    from veusz.plugins import ImportPlugin
    """initialize"""

    def doImport(self, params):
    from veusz.plugins import ImportDataset1D
    """Actually import data"""

importpluginregistry.append(ImportPluginExample)

    However, I think such behaviors are not intended. Such way becomes messy especially when users use some large classes. So I reported it as a bug.

    How to import the module scipy.interpolate into Veusz on Win10?

    I installed the Veusz on Win10 using the Latest Windows binary (64 bit) (GPG/PGP signature), but I do not know how to import the python modules, e.g. scipy.interpolate? I tried Edit --> Custom definitions --> Imports --> Module: Scipy.interpolate & Symbol list: griddata. The console gives me red marks: Error evaluating...: name griddata is not defined.

    I also tried install the python on my Win 10 system and set the python path from the preferences -> External. It still doesn't work.

  • Zeroes in

    Zeroes in "Symm. errors" column cannot be overridden with Pos. or Neg. values.

    Hi,

    I created a barplot with initially given values in "Pos. errors" column. If I accidentally put any value in "Symm. errors" column, the column gets filled with zeroes which results in removing all existing positive error bars. Deleting the number in "Symm. errors" cell zeroes it, and the whole column becomes filled with zeroes which can't be removed.

    Ctrl+Z helps, but I think that there should be any other way.

    Thanks.

    Dear developer

    I cannot install Veusz 3.5.3 on Ubuntu MATE 20.04.05.

    It seems to be because it requires PyQt5 5.15.x where PyQt5 available for Python 3.8 on the system is 5.14.x.

    I installed PyQt5 5.15.2 from a 3rd party PPA, but "ValueError: PyCapsule_GetPointer called with incorrect name" and cannot start it.

    When I remove the PyQt5 3rd party PPA and put PyQt5 back in, Veusz is now 3.0, far past the 3.4 I had been using, and I cannot open the files I was using yesterday.
