Thank you Robert,
   I am sorry I am reallylost in this search for the "systemd-analyze plot > plot.svg."  I looked for plot.vg in my "Search your computer and online sources" and found it.  When I clicked on it, it came out "unavailable data"!  I googled "systemd-analyze plot" and found this title.  When I opened it,  wow  I could not understand a bit about it.  I had expected a software to download and install it.  I don't know if it is already installed in my PC or not.  Did I miss it?  

UBUNTU MANPAGE: SYSTEMD-ANALYZE - ANALYZE SYSTEM BOOT ...

Recently my Ubuntu 15.04 was updated.  I had hoped that the bugs were already fixed, but still the same problems as before! When I clicked on the mentioned plot above, it came out with nothing in it ... just blank graph ... unreadable.
