For this exampe, we're assuming that you're trying to plot some factor variable on \( x \) axis and \( y \) axis holds some numeric values.Jan 16, 2017 · The stacking behaviour of geom_bar has been reversed such that the order of items is the same as in the legend. This seems not to be suitable when bars are horizontal orientated (apply coord_flip()). How do I reverse the order the stacked bars themselves, so that level 1 is at the bottom, and level 5 is at the top of each bar? I've seen a number of questions on this (e.g. How to control ordering of stacked bar chart using identity on ggplot2 ) and the common solution seems to be to reorder the dataframe by that level as that what ggplot is ...How to plot factors in a specified order in ggplot.

If the chart for which you want to change the plotting order displays axes, you can quickly reverse the order in which the categories or values are plotted along those axes.
