recetox-barplot help
=====================

Overview
--------

recetox-barplot allows creating barplots from tabular/csv/parquet data. On the input, data in a long format are expected, meaning that each column represents a variable, each row represents an observation as shown below.

User has to define which column holds the quantitative information (e.g. counts for particular category) and which column contains the categories to be plotted. It is also possible to use another variable to color the bars. Finally, `Use position dodge?` parameter defines whether the bars will be stacked above each other (default behavior when set to FALSE) or will be placed side-by-side (when set to TRUE). If no color column is supplied, setting this parameter will have no effect on the resulting barplots.
