## How can I format multiple thousands of date-dependant data points in a readable graph with Matplotlib?

I have two corresponding lists, one of the dates and another of its respective price. The lists are 30,000 data points long.

How could I add trendline to a dot graph drawn using matplotlib.scatter?

I would like to scale the `markersize`

of `matplotlib.pyplot.Axes.scatter`

plot based on the number of points on the x/y-axis.
