Re: [weewx-user] Re: Current wind graphic?
Thanks for the tips on color, Glenn. (Thanks also for providing a live example of how this looks.) I hope someone can come up with a more attractive color combination that provides enough contrast between wind and gusts, without clashing. Colors are not my forte. Just ask my wife. The other thing I'm less than happy with is the fatness of that gust pointer. It needs to be significantly larger than the wind pointer, so it's visible when they're pointing in the same direction. But it's really ugly. At present, I'm trying this as a substitute for the gust pointer definition: I think it's a slight improvement.

Re: [weewx-user] Re: Current wind graphic?
For any one else who wants to tweak the colours to match their weewx skin.conf of choice. It's worth noting the hint that's in the [ImageGenerator] section of the Standard skin.conf file # Colors can be specified any of three ways: # 1. Notation 0xBBGGRR; # 2. Notation #RRGGBB; or # 3. Using an English name, such as 'yellow', or 'blue'. # So, 0xff, #ff, or 'blue' would all specify a pure blue color. The existing skin colors are probably in the first format. To use those values in the svg windrose they needs to be changed to the 2nd format. Note the BGR -- RGB reversal and you'll be less likely to be surprised by the weird results ;-) Cheers Glenn rorpi - read only raspberry pi & various weewx addons https://github.com/glennmckechnie On 6 April 2018 at 05:36, RobbH wrote: > I finally came to the realization that everything I wanted to do could be > done with the Cheetah engine, and even learned a tiny bit of Python in the > process.

Re: [weewx-user] Re: Current wind graphic?
Thanks, Tom! You made my day.
About other measurement units, the log scale in the graphic works with
values from 1 to 100, and possibly a bit beyond. I think that might work
reasonably well for knots and km per hour, but probably not for meters per
second.

If you want to use javascript, you might be interested in this project
of mine:
github.com/wrybread/Weather-Underground-Style-Real-Time-Gauge
Personally I think javascript is a good method for current wind
conditions, since it makes it easy to update a graphic continually. This
live demo should update every 2 seconds or so (every time the wind
indicator turns green is an update):
sinkingsensation.com/wu_gauge/
I should really update that though, since it's very small on my screen.
A CSS issue. Or here (css optimized for mobile):
sinkingsensation.com/wind
Note that this requires enabling the RTC ("real time gauge") extension
in weewx. And fyi the effect is achieved by rotating the circle to the
current wind direction.

For future reference, if the graphic linked in the previous post is no
longer available, just save the svg code (everything but the '#import math'
line) to a file, rose.svg. Open it in a text editor, then replace the two
lines of text declaration and the two "if" blocks, all following the final

Re: [weewx-user] Re: Current wind graphic?
Interesting, Nice and simple too.
Just dropped the code into the main index template here and it works well.
I'm using Metric and kph ( km/h ) here and I don't see anything
unusual in its scaling.
http://203.213.243.61/weewx/
In fact, it's probably a keeper. Just need to find a more suitable
spot to place it.

If you want to use javascript, you might be interested in this project
of mine:
github.com/wrybread/Weather-Underground-Style-Real-Time-Gauge
Personally I think javascript is a good method for current wind
conditions, since it makes it easy to update a graphic continually. This
live demo should update every 2 seconds or so (every time the wind
indicator turns green is an update):
sinkingsensation.com/wu_gauge/
I should really update that though, since it's very small on my screen.
A CSS issue. Or here (css optimized for mobile):
sinkingsensation.com/wind
Note that this requires enabling the RTC ("real time gauge") extension
in weewx. And fyi the effect is achieved by rotating the circle to the
current wind direction.

A crude version, without making the wind directional pointer

[weewx-user] Re: Current wind graphic?
I finally came to the realization that everything I wanted to do could be
done with the Cheetah engine, and even learned a tiny bit of Python in the
process. The following code, added to index,html.tmpl (or some other
template) generates a crude compass rose with up to two directional vanes,
one (in red) for gust direction and one (in blue) for wind direction. The
length of the vanes is proportional to the corresponding speed value, on a
logarithmic scale.
#import math
http://www.w3.org/2000/svg";>
100
10
1
N
S
W
E
$current.windGust.formatted
$current.windSpeed.formatted
#if $current.windGustDir.formatted != " N/A" and
float($current.windGust.formatted) > 0
#set $wg = 65 - 18 * (1 +
math.log(float($current.windGust.formatted), 10))
#end if
#if $current.windDir.formatted != " N/A" and
float($current.windSpeed.formatted) > 0
#set $ws = 65 - 18 * (1 +
math.log(float($current.windSpeed.formatted), 10))
#end if
This is set up to work with speeds measured in miles per hour. Some
modification would be needed to make it work with other units. I hope
someone will find it useful. Improvements welcome.

Very nice! That's not exactly what I'm attempting right now, but I'll keep
in mind for the future.
I hope you'll add it to the weewx wiki, so it'll be easy to find in the
future.
I didn't find the realtime gauge data extension in the wiki, either, but
found it here:
