Year. We then instruct ggplot to render this as a stacked bar plot by adding the geom_bar command. Ggplot ce aes x Date y percent_weight fill Cultivar geom_col 384 See Also.
Since visualization is an essential part of data analysis we should make sure that the plots are created in a form that is easily readable for users. Finally position_fill shows relative proportions at each x by stacking the bars and then standardising each bar to have the same height. By default ggplot2 bar charts order the bars in the following orders.
