How do I plot a line in Matplotlib?

Controlling line propertiesUse keyword args: plt. plot(x, y, linewidth=2.0)Use the setter methods of a Line2D instance. plot returns a list of Line2D objects; e.g., line1, line2 = plot(x1, y1, x2, y2) . … Use setp . The example below uses a MATLAB-style function to set multiple properties on a list of lines.
