Faceting is data visualization technique, that partitions the plot into a matrix of panels. Each panel shows a different subset of the data. The subset of data is generated by dividing the main data set by some discrete or categorical variable.
There are two types of faceting:
- facet_wrap( )
- facet_grid( )
- facet_grid( ) produces 2D grid of panels, and uses all combinations between two categorical variables to create a sub-plots. Thus, if the data for some combinations is not available, it leads to empty sub-plot.
- facet_wrap( ) produces 1D chart but wraps it in 2D. Since it is essentially 1D chart, there are no empty sub-plots created using facet_wrap( ) function.
we will use gapminder data-set to create facets. We will also use some useful techniques that can be used to modify the facets in terms of Axis scales and plot layout.
