Other implementations exist (namely from ggplot2) that provide extensive customization.This package provides an alternative implementation that relies solely on base graphics, yet still provides methods for data.frame, matrix, … A box plot (or box-and-whisker plot) shows the distribution of quantitative data in a way that facilitates comparisons between variables or across levels of a categorical variable. The process is fairly straightforward in Stata (and even easier in Matlab…). You can either add the function direclty in your code (see violin-plot.js) or … Statistical Software Components from Boston College Department of Economics. The violin plot combines the basic summary statistics of a box plot with the visual information provided by a local density estimator. ... Violin Plot. Groups must be provided to x, subgroups … 02. Plot multiple kernel densities on one plot in Stata If you want to compare kernel density estimates across years for a particular variable, putting each estimate on one graph will make it easy. The violin plot is very similar to a combination of a density chart and a box plot, with the key difference being that I have also plotted the mean, and I have used a line to indicate the entire range of data so that the viewer can see the extent to which the tip of the plot are just extrapolations versus real data. Box plots are great as they do not only indicate the median value but also show the variation of the measurements in terms of the 1st and 3rd quartiles. A glyph is a geometric object made with data visualization software that represents the values of each quantitative variable. Ggplot2 allows this kind of representation thanks to the position="dodge" option of the geom_violin() function. Notes: 1) This function is not perfect. More details on the plot can be found in: Hintze, J. L. and R. D. Nelson (1998). It is a blend of geom_boxplot() and geom_density(): a violin plot is a mirrored density plot displayed in the same way as a boxplot. I want to plot the Violin Graph with my data, but I am not able to get how to plot those graphs. Violin Plot.
