  2D arrays • So far, we have been working with one dimensional arrays (e.g. array([1,2,3,4,5,…]) • With “matching” 1D arrays for x and y we can plot 2D data- such as position vs time. Each “data point” contains two pieces of information: x, and y (or time and position). • A 2D array allows us to plot 3D data points- …
