Solr Dashboard JVM-Memory chart, what do the two marks mean?

Question

The Solr admin console has a chart on it called "JVM-Memory", which might look for example like this:

I think this means my JVM max size (-Xmx) is 2GB. And it's currently using 98.4MB of JVM RAM (4.8% of 2GB).

So, what is that other line at 854MB, the light grey bar? What does that mean?

I have not successfully found any documentation of this Solr admin dashboard UI by googling. The chart doesn't have any mouseovers or on-screen explanations.

Anyone know?
