Running hammer results in chart with no data

[McDoit]

Trying to run the hammer, console shows output but chart is empty
Drill and nailgun works and gives charted data

Tested in 1.1 and 2.0

Steps to reproduce

1. run ltt hammer -u https://www.google.com -m GET --min 5 --max 10 -f chart-hammer.png
2. check chart
3. nothing.

Expected behavior

• chart should show data

Observed behavior

• empty chart

Confirmed: I'm seeing some weird stuff with low min/max request amounts.
