 I added screenshots.

 If you use option `graph_bound tight`, you should be able to reproduce it
 (it is seen immediately after starting Nyx). You can see on `*_before.png`
 attachments, that only single 'impulse' is plotted, and its value is
 really high (3 MB/s for download, and 2 MB/s for upload). After this
 'impulse' passed out, all values are calculated correctly (`*_after.png`
 attachments: few 'impulses', each with 3 B/s for download, and 543 B/s for
 upload).

 Tor was not used by applications during these measurements. Tell me, if
 this is not enough for you.
