Matplotlib – Line Plot Examples Example 1: plotting two lists. If zooming in on a plot when using float arguments then the actual data points that have markers will change because the distance between markers is always determined from the display-coordinates axes-bounding-box-diagonal regardless of the actual axes data limits. It was introduced by John Hunter in the year 2002. We can even create a dataframe and use the data to create our plot. Let's see what happens if we change the distribution: The first couple of values sets the scale. There are various ways to plot multiple sets of data. matplotlib Line plots Example Simple line plot.
