histogram tests: data #124

Closed lwasser closed 4 years ago

lwasser commented 5 years ago

INstructor helper content - let's think about this . more

  1. For histogram data tests. What if we have a wrapper that accepts a mpl plot. and returns the data for a histogram (i could see us doing this for other plot types as well). This might entail pulling out some of the code from the assert statements into helper functions that grab the data from the plot.
  2. we can make the function "smart" to test for how many columns are in the data.

closing because we do test for bin heights or the data values... and we are not going to implement the smart helper for the time being. ...
