How can I count the number of batches independently of samples?
I have a series of batches produced over a period of years for which a different number of samples have been taken; e.g. see Table below. I want to be able to graphically visualise the number of batches per year but I cannot seem to be able to do that without having to build a new table in which I remove the repeats; i.e. the samples column. Is there an easy way to count and/or visualise the numbe...
