Hello, Tarmo
One of the images that you are trying to generate has an option y_scale
<http://www.weewx.com/docs/customizing.htm#Plot_scaling_options> with a
min_interval of zero, or less than zero.
Look in the file /home/weewx/skins/Seasons/skin.conf for images that use
y_scale. They will look something like this:
yscale = 10, 20, -1
or like this
yscale = 10, 20, 0
The "10" and the "20" do not matter. It's the last number that we care
about. It cannot be less than or equal to zero.
If you're having trouble, post the file skin.conf.
