Circle (xy, radius = 5, ** kwargs) [source] #. patches. pyplot. The plot function will be faster for scatterplots where markers don't vary in size or color. Image. array(PIL. An RGBA (where A is alpha, or transparency) has 4 values per inner list, and a simple luminance image just has one value (and is thus only a 2-D array, not a 3-D array). Valid kwargs for the marker properties are: contour and contourf draw contour lines and filled contours, respectively. 6 trillion miles, or approximately 266,000 astronomical units, or AUs. The data input x can be a singular array, a list of datasets of potentially different lengths ([x0, x1, ]), or a 2D ndarray in which each column is a dataset. I used the following code based on a previous example of plotting 2d vectors but added components for 3d vectors. Many of these instances methods simply forward to the corresponding matplotlib Axes instance method, with some extra pre/post processing and argument checking. contour and contourf draw contour lines and filled contours, respectively. It can speed up rendering and produce smaller files for large data sets, but comes at the cost of a fixed resolution. Each pyplot function makes some change to a figure: e.
