Plot binary image python
WebbThe first step to plotting an image is to actually load the image into our Python program. This can be done through a variety of methods, out of which imread () is the most common. This function takes an image file path and returns the image data for that image for us to use. 1 2 3 import matplotlib.pyplot as plt img = plt.imread ("quiverplot.png") http://scipy-lectures.org/packages/scikit-image/index.html

If you provide a single list or array to plot, matplotlib assumes it is a sequence of y values, and automatically generates the x values for you.Since python ranges start with 0, the default x vector has the same length as y but starts with 0; therefore, the x data are [0, 1, 2, 3].
WebbI'm using python to simulate some automation models, and with the help of matplotlib I'm producing plots like the one shown below. I'm currently plotting with the following command: ax.imshow (self.g, cmap=map, interpolation='nearest') where self.g is the binary map ( 0 -> blue, 1 -> red in my current plots).
