Yes, Schweizer Hochdeutsch is standard German without the ß, and some local words uncommon in Austria or Germany. Basically this is what newspapers as the NZZ are written in.
Schwizerdütsch are the Upper German dialects spoken in Switzerland and around, which, if written down at all, like OC said, don't follow a standard orthography.
Thus, you can find Schweizer Hochdeutsch on the chart, but not Swiss German, Schwizerdütsch.
