attached is a (German...) bar chart which shows the five possible values of the one variable "Culture": Nix, BV, Candida, Mix, Unspecific.
The variable is measured at three different times, 1 (blue), 2 (green), 3 (something).
I am looking for some kind of test to determine that the number of measured individual values increase, or decrease. For example, I'd like to show that over time (i.e. from time=1 to time=3), the value "Nix" is measured more often, whereas "Candida" and possibly "Mix" go down.
I am a bit confused because we have three time points and five possible values, this makes it a bit unclear for me.
