I switched to this from the PolarWindPlot as it didn't work on bullseye & python 3.9.2. However unlike the PolarWindPlot it doesn't offer the same range of types of plot, most of all the Spiral. I was using this and would be very happy if the spiral starts working again.

     [[SpiralScatterTrailSpecific]]
         [[[dot4spiral]]]
             plot_type = spiral
             marker_type = dot
             marker_size = 4
             [[[[windSpeed]]]]

Hi,

In latest index.html.tmpl, the plots are decided by plotgroups and it checks obsType for each plot group and if it has data. This does not work with stackedWindRose extension.

Hi,

Had my station going down couple of time yesterday which has resulted in probably some missing data. As a result of this, speedVec is None for some entries. At line 273 of imageStackedWindRose.py, we check max of speedVec[0] which errors out if some entries are None. To avoid this I locally edited as below:

Refer this WeeWX user group thread.

Currently petal colours applied to a percentage range of speeds (eg the bottom 10% of speeds are green etc) so over time a given colour represents a varying band of speeds. It would be useful to assign petals colours to bands of absolute speeds (eg 0-2 km/hr is green).

Hello,
Can anybody help regarding the Windrose code?
I update my weewx to latest version 4.1.0 and change the recommended python 3 version but afterwards the windrose doesn't work!

It would be great if anybody have an idea what's going wrong and can help me.
At the moment i didn't see a chance to update the latest weewx version.

I restore my old one and run again 3.9.2
