By then clicking the "unmerge" button next to "tissue" the single bar chart will expand with tissue clusters.
In these ways the new barChartFacets, barChartStatsUrl, and barChartMerge settings allow users to explore the barChart data on the individual details page more closely. One can use the facets -to further select certain types and also click the columns (val/count/cluster) to arrange -by numerical value or alphabetical name.

The setting +singleCellColumnNames off can be added to the trackDb to change the display +column to count instead of the default display cell count. This setting is useful for +non-single-cell datasets such as bulk RNA-seq, where count represents the number of samples +or replicates rather than cells.Also, if you click the "Return to Genome Browser" link, you will see only these selection bars are displayed.
In this image after making the selections browsing ACE2 the "zoom out" button has been clicked to also view nearby genes where the expression of these tissue selections for the gene PIR is quite noticeably different.
In this example, we will be using command-line tools that were used to create the single-cell tracks available on hg38. For more in-depth examples of these tools, take a look at the following
