Wind rose - why the unusual shape not radial segements
I've been wondering why the Wind Rose gauge (I know it is not a standard Steelseries gauge) does not use the format commonly used for wind roses, eg see
http://en.wikipedia.org/wiki/Wind_rose which seems much more meaningful that the 'ink blot'.
Would it be too difficult to achieve?
Having just despiked my Fine Offset data (by smoothing the data to fill in the deep valleys, redistributing the peaks to rectify the undercounting of the 8 minor cardinals) I start to think the wind rose could be more useful if done in a set of 'pie slices'...I find the 'ink blot' shape visually confusing, probably just my tired old eyes
Only if Mark is interested, of course!

It requires a lot more data is one problem, data that would be hard to get out of Cumulus. There are Wind Rose components around that we could use, but I think you would need your data in a database to extract and process it in the required manner.

Re: Wind rose - why the unusual shape not radial segements
Thanks Mark, I realise that the pies couldn't easily have wind speed applied (so a single colour) just so they were 'flat ended' rather than the edge sloping acutely so variation is lost to the eye... sort of like this...
I suppose one could do a second colour for gust.

That's a lot of wind variation, Stuart!Stuart2007 wrote:Thanks Mark, I realise that the pies couldn't easily have wind speed applied (so a single colour) just so they were 'flat ended' rather than the edge sloping acutely so variation is lost to the eye... sort of like this...

Not much wind, William, but lots of variation. You don't seem to do wind down your end at present!

Stupid Oak Trees, that block me from the WNW, NW and NNW! Very popular wind directions down here, I want to chop them down, ASAP!Stuart2007 wrote:Not much wind, William, but lots of variation. You don't seem to do wind down your end at present!

Re: Wind rose - why the unusual shape not radial segements
Wow wow wow, I'm really impressed! Just the job! Can I use that, but with 16 segments? Is the code in windrose.js? Can I recolour it, and preferably grade the colour from Centre to outer edge?mcrossley wrote:What, like this you mean?

I think even better with 22.5% pies - I've got my averaging going to even out the data for the slices see below:
The smoothing function is just that any point = itself +25% of each either side, which assumes that the minor reedswitch is only actuated 1/3 of the time it should be.
This seems much better than just ignoring the minor 8....imho

Yes, I think I will use this for the next release.Stuart2007 wrote:Can I use that, but with 16 segments?
Yes, but you also need a new RGraph libraryStuart2007 wrote:Is the code in windrose.js?
Yes, I think the RGraph rose supports gradients.Stuart2007 wrote: Can I recolour it, and preferably grade the colour from Centre to outer edge?
Let me work on it for a bit, I will add some code to reduce the segment gaps as you increase the number of segments, it also looks like I need to customise the RGraph library a little (already made one change on the copy used above).
v2.2.0 of the gauges was ready to go, a bit more work to do now

Re: Wind rose - why the unusual shape not radial segements
Ah, and I remember the problem with the rose now - the segments do not line up with the cardinal points, I will have to add another patch into the RGraph library to fix that.

Brilliant - you are always moving in the right direction! I will certainly use it (16 points).Yes, I think I will use this for the next release.

Yes, it looks like you have segments which need rotating 22.5deg to point at NESW cardinals rather than between them.
I think my extra gauge code for Mill Heading in gauges.js means I will have to merge my bits into any new version of gauges.js...

Re: Wind rose - why the unusual shape not radial segements
I fixed that last night, I also put a request in to the RGraphs author to make that orientation a standard option in his library.Stuart2007 wrote:Yes, it looks like you have segments which need rotating 22.5deg to point at NESW cardinals rather than between them.
