The list is fairly low-traffic. In one of the future tutorials I'll cover PyQt threading, this one is focused on just the bare basics We create a widget called PlotCanvas that includes the Matplotlib plot. Pyqtgraph 16. PyQtGraph is based heavily on Qt’s GraphicsView framework–if you are not already familiar with this, it’s worth reading about (but not essential). INTRODUCTION. + To use with a specific project, simply copy the pyqtgraph subdirectory anywhere that is importable from your project. But others seem to run pyqtgraph with something called jupyter or alternatively another package called panda. In most cases, however, it will be unnecessary to call these functions directly–any function or method that accepts pen or brush arguments will make use of these functions for you. Topics: For 3D graphics: pyopengl and qt-opengl; Known to run on Windows, Linux, and Mac. I've built a number of applications that plot data from a variety of microcontrollers in real-time to a graph, but that was really more of a two-step process: 1. I don't think I am alone, since this seems to be the pinnacle of understanding the basics of OpenGL. Both editions can be built for Python 2 and 3. One of these applications, three-dimensional (3D) CT with volume rendering, is now a major area of clinical and academic interest.

The Python Computer Graphics Kit is a collection of Python modules that contain the basic types and functions to be able to create 3D computer graphics images. Another really great tool I've used for creating dashboards is Metabase. The rstride and cstride kwargs set the stride used to sample the input data to generate the graph. Now pyqtgraph does have a bar chart class, BarGraphItem. Adjusting the appearance of the scale labels Since scale labels play such an important part of producing a visually pleasing graph there are a number of ways to fine tune this appearance. An example which shows how to plot a surface from data acquired irregularly.
