Python Question

Matplotlib connect scatterplot points with line - Python

I have two lists, dates and values. I want to plot them using matplotlib. The following creates a scatter plot of my data.

import matplotlib.pyplot as plt


plt.plot(dates, values)
creates a line graph.

But what I really want is a scatterplot where the points are connected by a line.

Similar to in R:

plot(dates, values)
lines(dates, value, type="l")

, which gives me a scatterplot of points overlaid with a line connecting the points.

How do I do this in python?


I think @Evert has the right answer:

plt.plot(dates, values)

Which is pretty much the same as

plt.plot(dates, values, '-o')

or whatever linestyle you prefer.
