Positions in histograms
Here, we'll examine the various ways of applying positions to histograms. geom_histogram(), a special case of geom_bar(), has a position argument that can take on the following values:
stack(the default): Bars for different groups are stacked on top of each other.dodge: Bars for different groups are placed side by side.fill: Bars for different groups are shown as proportions.identity: Plot the values as they appear in the dataset.
