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.

Under each call, modify the plot as desired before the creation of another subplot.

What are the advantages of a multiple line graph?

Multiple line graphs have space-saving characteristics over a comparable grouped bar graph. Because the data values are marked by small marks (points) and not bars, they do not have to be offset from each other (only when data values are very dense does this become a problem).

What is multiple bar graph?

A chart depicting two or more characteristics in the form of bars of length proportional in magnitude of the characteristics. For example, a chart comparing the age and sex distribution of two populations may be drawn with sets of bars, one bar of each pair for each population, and one pair for each age group.
