Some convenience classes for scientific plotting in Qt

QPlot

A library of for scientific plotting with Qt Widgets / C++.

Contains the following:

• Simple containers for list- and map-based histograms (QHist.h)
• KnightRiderWidget for scalar value visualization
  
• qcustomplot (v2.1.0)
• Convenience classes based on qcustomplot
  • QPlot1D for 1-dimensional histogram widgets
  • QPlotDraggable for selecting points and ranges in 1d plots
    
  • QPlot2D for colormap widgets
    
  • GradientSelector widget with visualization for color map gradients
    

A conan package of the library is available on the ESS Artifactory.

Apologies for the lack of documentation. You can build doxygen API docs with make api_doc, though there is little in terms of descriptions. The test subdirectory contains some interactive examples of how each widget is to be used. You can also glean examples of usage in the following projects that make extensive use of this library:

• daquiri
• events-nmx-classify
• qpx-gamma

qplot's Issues

Value on under mouse for colormap plots

Provide convenient way to access rubberband-based zoom

Enable OpenGL

Write doxygen documentation for all classes

Make it work on CentOS

Gradient selector needs parent for modality

Emit signal for change in 1d plot thickness

Logarithmic ticks

Increase hist type resolution

Might want to use uint64_t for histogram types

Consider adopting different plotting library

There is this:

might be more minimal and not dependent on Qt, but then it might lack some abstractions and require way more work to get the same interactive functionality. Advantages are not clear, pending further investigation

STICKY: update upstream libraries

STICKY: This issue can stay perpetually open, so it can be linked in a persistent maintenance branch.

This essentially consists of:
https://www.qcustomplot.com/

The code should periodically be updated with that downloaded from the author's website.
The README should also be updated on such occasions.

STICKY: Keep CI scripts updated

STICKY: This issue can stay perpetually open, so it can be linked in a persistent maintenance branch.

Goal: keep CI scripts updated and ensure the library builds on recent operating systems and distributions.
