It's still supported. When using multiple -a options, popup the Open View
dialog and the host/archive selector there should list each host separately
(it does here for me, anyway, with git master pcp).

Is that from a mkaf(1) folio? The patch below might be of use, it adds in
a --archive-folio option so that they can all be opened directly from the
folio, rather than listed separately.

Hmm, looks like kernel.all.cpu.sys is missing from one of the archives? And
since no host specified for the plot, IIRC think it will use the first listed
host on the command line. (or perhaps last)

You may be looking for the "host" keyword in the pmchart(1) view configuration
language? - allows an individual plot to be explicitly associated with a named
host.
cheers.
