Wind in graphs when there´s no wind because it´s calm

Is there a chance to change the drawing for wind direction in graphs.

Wind directions values are also shown when the current condition is calm.
That is a confusing point if you look at a graph.

Here´s an example what I mean:

How easy might it be to alter the meteohub code and having all wind direction values disappearing when "wind speed=0" ?

Cheers,
W.

Hi,
I don't know of a simple way to do this, because gnuplot does the drawing.

Introducing something like "no direction" in the aggregated data for gnuplot might have quite a few side effects. I will think about it.

In some software (I can't recall if it is WD or WSWIN or both) I think I've seen a (probably optional) feature that direction should report as a specific value (0?) when windspeed is zero.

You choice may vary... :)

WSWIN is the one, where I got it from ;)
