I'm currently trying to present my data but I'm having some trouble deciding what graph to use...
I'm studying the effect of alcohol concentration on gene expression.
I have two categorical variables. One is the alcohol concentration (0, 1 and 2 %) and for the other I've graded gene expression in my samples from 1 - 4. For each concentration i have three groups and in each group i have around 4 samples.
I was thinking on doing a boxplot but I'm not sure if i have to have continuous data on one of the axis?
any help would be appreciated!
