By default, it is TRUE, which implies How to make a heatmap in R with a matrix. I can generate a density plot of 1D data with: qplot(mydatapoints, geom='density') I've also seen plenty of examples of heatmap grids, but these are more akin to histograms for 1D data in that data To visualize data distribution in a matrix or in a list, we normally use boxplot or violinplot.
