Just as with any other chart type you have learned so far, scatter charts can also be plotted with multiple series.

Copy the code from the previous example and add another series for earthquake data for Ocotillo, California:

{
  name: 'Ocotillo',
  data: [[0.1, 5.0], [4.6, 4.6], [4.4, 4.6], [2.3, 4.5], [10, 4.4], [10, 4.2], [4.9, 4.0], [0.4, 4.5], [13.6, 4.9], [14.4, 4.8], [0, 4.7], [3, 4.6], [6, 4.6], [1.2, 4.5], [6.8, 4.5], [12.6, 4.4], [5.6, 4.4], [10, 4.2], [1, 4.1], [0.5, 4.0], [14.1, 4.0]]
}

The series for Ocotillo will be added to the previous chart.
