[weewx-user] Re: Increasing image size within Seasons skin
Adding a second change will correct the bottom_label if I'm using my new
time_offest - simply subtract the offset in line 175 from plotgin_ts:
# Get a suitable bottom label:
bottom_label_format = plot_options.get('bottom_label_format',
'%m/%d/%y %H:%M')
bottom_label = time.strftime(bottom_label_format, time.localtime(
plotgen_ts - int(plot_options.get('time_offset', 0
plot.setBottomLabel(bottom_label)
Not a very elegant approach (to have this calculation at 2 places within
the code), but it works fine.

Thanks for that hint - currently I'm still experimenting with this new
functionality.
In the meantime I could resolve my problem with seasons.css - it was a
problem with caching within firefox. Even after deletion of
/var/www/htmp/weew/seasons.css firefox did render it after reload/refresh.
But when new images have been generated the missing seasons.css become
obvious, and a new seasons.css will be used. Thus one problem solved!

[weewx-user] Re: Increasing image size within Seasons skin
I've digged a little bit within source code of weewx - especially
bin/weewx/imagegenerator.py
My goal is to shift the timeline by an offset so that I can render data
from the "future" (from the DWD forecast). And to my surprise it's really
simple to introduce the new option time_offset by adding only one line of
code into imagegenerator.py
...
# Calculate a suitable min, max time for the requested time.
plotgen_ts = plotgen_ts + int(plot_options.get('time_offset', 0))
minstamp, maxstamp, timeinc = weeplot.utilities.scaletime(
plotgen_ts - int(plot_options.get('time_length', 86400)),
plotgen_ts)
x_domain = weeutil.weeutil.TimeSpan(minstamp, maxstamp)
...
Within skin.conf I've added this "new" option time_offset = 259200 (3
days), and I get the intended shift of the timeline by 3 days (see appended
image).
The only disadvantage is that the timestamp printed below the image is
shifted, too. But I think that is by design (same for wee_report with
timestamp option).
My suggestion: Please include my small change within the next release of
weewx.

I tested with Firefox (windows x64) and Apache server.
Use F12 and inspect where the size directive is coming from, if you
feel brave.

[weewx-user] Re: Increasing image size within Seasons skin
I've done more experiments w.r.t. time_enght - if I increase its value by 1s from the default 27h I get an imagecoverring 48h (instead of 27h plus 1s). Thus the value 97200 is kind of magic to deliver the expected 27h, but it's not possible to increase the value even a little bit. See my appended picture with time_length = 97201.
