I was thinking about a way o PyQtGraph offers the functions mkColor(), mkPen(), and mkBrush() to simplify the process of creating these classes. The kit mainly focuses on Pixar's RenderMan interface, but some modules can also be used for OpenGL programs or non-RenderMan compliant renderers like POV-Ray, for example. plot(). + To use with a specific project, simply copy the pyqtgraph subdirectory anywhere that is importable from your project. 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. History serves many purposes, but one of its more important functions is to provide us with a reference point so that we may see how far we’ve traveled. The example above would open a window displaying a line plot of the data given. 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. Plotting level curves Plotting level curves (isocurves) with pyqtgraph. 7.
