It is known that the number of each bead type to be found on an array follows a Poisson distribution with a mean of around 30. This plot helps us to see how well this assumption is met. If too many bead types have less than 30 beads it might indicate a problem with the array and compromise the robustness of the experiment.
We show a Poisson distribution with mean ~50,000 / 1500 on top of the histogram so it can be seen how different the numbers of beads we observe is to how many we expect to see.
Histogram is plotted.
