Well on first look it looks like the overrides in weewx.conf are not being picked up, looking closer at the stacked windrose generator code I can see that the overrides are being picked up but the generator never does any conversion of the raw wind speed data from the database. In terms of effects, this means the windrose would always use the speed units that are used in the weewx database (for most this is mph). Not sure how I missed this, that generator was written over 2 years ago and I distinctly remember testing the units - perhaps it coincided with changing database units on my then test system - I do remember doing that a few times. No matter.
To fix the issue just move aside your current bin/user/imageStackedWindRose3.py then download the latest version of the file from bitbucket. Easiest approach to downloading is probably using wget - this command should do it: $ wget -P /var/tmp https: //bitbucket.org/ozgreg/weewx-wd/raw/bc5c32cd97e5ec7f81ea8f83eb0edb2f241eaa3f/bin/user/imageStackedWindRose3.py Note this file has the import Image/ImageDraw fix from a few days ago so that issue should not give you any more grief. Thanks for pointing out the issues.
