In depth
A closer look at PyQtGraph
Built on PyQt4 / PySide and NumPy, PyQtGraph is a graphic and GUI library whose primary purpose is to offer reliable graphics for displaying data while being a responsive companion in application development as well.It is also worth mentioning that the software utility relies on the Qt GUI platform in order to ensure high-quality graphics and on NumPy for heavy number crunching.The array of the software’s capabilities is quite broad, including all of the following and even more. Basic data visualization primitives can be handled, with images, lines, and scatter plots being on the list. Then, interactive scaling or panning, averaging, SVG or PNG export are also possible.Support for widgets meant to mark or select plot regions or the image region of interest is guaranteed, with real-time update of the video or plot data being once again a certitude.What’s more, a 3D graphics system is integrated for volumetric data rendering, mesh rendering with isosurface generation, basic 3D scenegraph for a comfortable programming experience, and more.One of PyQtGraph’s main concerns are related to speed and interactivity followed closely by portability. As for the fields it could prove relevant in, it must be pointed out that it aims to be more than an ordinary plotting library, and living proof are the ImageView and ScatterPlotWidget analysis tools, the flowcharts, parameters trees, etc., which expand its area of interest towards science and engineering as well.
