Spot information / gene expression violin plot / box plot
in this section, users can visualise the gene expression or continuous Spot information
(e.g. Number of UMIs / module score) across groups of Spots (e.g. libary / clusters).
in this section, users can visualise the gene expression patterns of
multiple genes grouped by categorical Spot information (e.g. library / cluster).
The normalised expression are averaged, log-transformed and then plotted.
