My guess is that for the hard-to-see zig-zag line, the x-axis represents
disk addresses from 0% (beginning of the disk) to 100% (last block on
the disk), not time.  The y-axis for that line is on the right, in
milliseconds.  It seems to be a continuous trace of (%-of-disk, seek
time) points, all linked together in a chain, chronologically.

This contrasts with the left-hand y-axis which is in MB/s and applies to
the blue line across the top.  I agree that the x-axis percentages in
that case refer to time: the percent of the test period for each point.
Rather odd, I agree.

The data points for the most recent benchmark of each disk are cached in
~/.cache/gnome-disk-utility/drive-benchmark/*

The text should explain this, and in addition, the axes should use the
same color as the lines.

My other suggestion is to change the colors used for the zig-zag line.
I'm red-green colorblind and find it nearly impossible to see them.

Note: I also wish those benchmarks were archived, not just cached.  See a related request for that at
 "How can I log my SSD's read performance over time? - Ask Ubuntu - Stack Exchange"
   http://askubuntu.com/questions/8279/how-can-i-log-my-ssds-read-performance-over-time

Note also that the name of the gnome-disk-utility executable is
"palimpsest".
