Matplotlib connect scatterplot points with line - Python

Question

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 scatter dates values  plt show     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

In addition to what provided in the other answers, the keyword "zorder" allows one to decide the order in which different objects are plotted vertically. E.g.:

plt.plot(x,y,zorder=1) 
plt.scatter(x,y,zorder=2)

plots the scatter symbols on top of the line, while

plt.plot(x,y,zorder=2)
plt.scatter(x,y,zorder=1)

plots the line over the scatter symbols.

See, e.g., the zorder demo

For red lines an points  plt plot dates  values    r-      or for x markers and blue lines  plt plot dates  values   xb-

I think  Evert has the right answer   plt scatter dates values  plt plot dates  values  plt show     Which is pretty much the same as   plt plot dates  values   -o   plt show     or whatever linestyle you prefer
