The composition tab is meant to show what features comprise your dataset, and the groups within it (e.g. counts, proportions). If a date column is defined, it will be summed out. If no within-groups aggregation function is specified, and one is needed, the values will be added together.
Three geoms are available: bars, bars stacked, and pie.
The trends tab is is similar to composition, but adds the dimension of a of progressing time series. This requires a date column and format be provided.
The four available geoms are: lines, bars, area, and area stacked.
Like the composition plots, these plots will also sum the value if no other aggregation function is specified, with the exception of lines; it has unique behavior. With lines specified, if multiple observations exist per group (grouping by date, group, & feature), each observation will appear as a point, and a loess regression line will be included.
The distribution tab is useful for viewing a values dispersion and, well, distribution. For this reason, it is best not to aggregate the values.
Four geoms are available: histogram, density, violin, and boxplot.
An additional geom, “rug”, can be overlayed by checking Show Rug.
