I hadn't thought of that, but it would be trivial to add to the wind plot window.

I think you understood the point: at a quick glance at the windplot graph it is possible to know if the weather forecast is early, or late, or correct, or totally wrong, or underestimated, or overestimated, etc etc.

One could even imagine adding complexity to the WindPlot graph: for example in gray over a large area the GWD & GWS measurement, and in yellow dotted line the weather forecast X, in red dotted line the weather forecast Y, in blue dotted line the forecast weather forecast Z. At a glance you can easily understand what is happening. Saving time and efficiency. Of course, this remains a "decision aid" and not a function that we follow with our eyes closed. But in a situation of great fatigue (and stress? And difficulty in thinking clearly?) This can be an interesting supplement. And as you say, it doesn't seem technically complicated to me to set up such a graphics function.

Your English is better than my 35 year old French.

It isn't possible to send plots to B&G displays.

The grib line isn't on the wind plot, but I am looking at it just now. It is a trivial thing to add.
