ridge plot weird behavior when total number of pure and reliable taxa > 1000

First--the new plots are great!

I'm analyzing a relatively large 16S dataset and found some strange behavior in the ridge plots when a gradient has more than 1000 combined z-/z+ taxa and you try to limit the number of taxa plotted for readability.

Specifically, only the z- taxa will show, and at the bottom of the graph will be a mess of overwritten text that is the z+ taxa.

When you split the taxa plot (e.g. FALSE for plot z1) there is further weird behavior. Setting z2 to FALSE is fine--everything works as expected. Setting z1 to false works, but only 2-3 taxa are plotted, and they are very strange looking. I had to set the number of taxa plotted to ~300 to get roughly 60 to plot (this changes based on the titan output you're plotting).

Thanks!

Start by reproducing the ridge plot with more than 1000 combined z-/z+ taxa while limiting the number plotted, then compare split settings for plot z1 and z2. Check whether the plotted taxa and labels match the requested limit across these cases; done means both z- and z+ taxa render correctly without overwritten text or unexpectedly missing taxa.
