the "wind history" instrument is meant to be run as a standalone (vertical) instrument.
Just define a separate dashboard and add it as the only instrument.
See screenshot wind_history_setup.gif please.
You can / should (!) resize it with the mouse, see windhistory.gif
In real conditions, it monitors around 40 min of wind direction (red), as well as wind speed (blue), showing a vertical timeline every 5 mins (the example screenshot is a full-speed VDR replay).
The text on the top shows the current
values, as it is displayed in the standard instruments (blue = wind speed data, TWS=True Wind Speed
, red = direction, TWD = True Wind Direction
Here is an explanation of the text line, left side (see screenshot):
: true Wind Speed currently 7.5 kts
Max 22.3 kts since 18:50
: this is the max Windspeed in the visible (!) curve, i.e. the last ~40 mins
: the max windspeed since O was started.
right side :
: True wind direction currently 357°
The thin red/blue curves are the real direction/speed values, the thicker curves are smoothed values. Makes it easier to see trends.
There is some logic included :
The instruments re-zoomes automatically as much as possible, always trying to show the whole visible curve;
if your max (visible) windspeed is 10 kts, then your scale is from 0...11 kts (rounded upwards to the next full knot).
In the screenshot we had a mx of 22.3kts --> scale is 0...23 kts.
The instrument scale shows +/- 90° of the currently visible data values, but is limited to a total of 360°.
If the wind is shifting through North (from 350, 355, 359, 002, 010, ...) we're shifting the curve as well, meaning that there is NO
vertical jump in the data from 360° --> 0°, and we do NOT
loose all the continuity in the smoothed curves !
If you should happen to have more than a full 360° cycle of wind direction in the recorded data (if you sail through a couple of dust devils
), I limited the max scale to 360°, meaning that the curve will run out of the visible area on bottom or on top of the instrument.
Please note :
you don't have to have the instrument "open" all the time.
Once activated as initially described, you can close it, and simply reopen it on demand. You don't loose the curves, the instrument continues to collect the data.
Simply rightclick on the standard-dashboard, and set click the wind history
Well to be honest this is an dashboard-automatism and was not my programming :-)
