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.
