The navigation chart will be different with the main chart after aggregating data to firm 1px bar

After thinking about it, it might not matter, since we are going to set up the 500kbp window for interest of region and gene. At this level of window size, the data will not be aggregated. The bar will represent the original data from the readDepth endpoint.

The only concern is that the difference between the navigation and the main charts would confuse users.
