I have two lists, dates and values. I want to plot them using matplotlib. The following creates a scatter plot of my data.
JavaScript
x
5
1
import matplotlib.pyplot as plt2
3
plt.scatter(dates,values)4
plt.show()5
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:
JavaScript

1
plot(dates, values)2
lines(dates, value, type="l")3
, 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:

1
plt.scatter(dates,values)2
plt.plot(dates, values)3
plt.show()4
Which is pretty much the same as

plt.plot(dates, values, '-o')2
plt.show()3
You can replace -o with another suitable format string as described in the documentation.
You can also split the choices of line and marker styles using the linestyle= and marker= keyword arguments.
