Ggplot Bar Plot Order By Value. Visualise the distribution of a single continuous variable by dividing the x axis into bins and counting the number of observations in each bin. Frequency polygons are more suitable when you want to compare the distribution across the levels of a categorical variable.
A third approach is to map the value but override the default scale. Histograms geom_histogram display the counts with bars. Often we do not want just some ordering we want to order by frequency the most frequent bar coming first.

This can be achieved in this way. The first use arrange to sort your data frame and reorder the factor following this desired order. The second specifies a custom order for the factor giving the levels one by one. A third approach is to map the value but override the default scale.
