Instructions:
Put results into the fields in the center.
Press the [1] or [2] boxes to load in my results from my microbiology class. (More helpful for me, but it gives a good demo).
Toggle the "Allow Missing Data" to allow or disallow data that is not there.
Mouse over the bars to see their stats. The percentage is how many of the variables are either positive or have no data. The numbers are [Number positive/missing]/[Number that have data]/[Total number].
