EDA: Plotting earthquakes over time

Make a plot where the y-axis is the magnitude and the x-axis is the time of all earthquakes in Oklahoma between 1980 and the first half of 2017. Each dot in the plot represents a single earthquake. The time of the earthquakes, as decimal years, is stored in the Numpy array time, and the magnitudes in the Numpy array mags.

  • Plot the magnitude (mags) versus time (time) using plt.plot() with keyword arguments marker='.' and linestyle='none'. Also use the keyword argument alpha=0.1 to make the points transparent to better visualize overlapping points.
  • Label the x-axis 'time (year)', y-axis 'magnitude', and show the plot.
