[Xcsoar-user] Map display questions

[Steve F. <st...@fr...>]

Thanks for all the advice on simulating thermalling. Replaying a previous flight answered all my questions except 3. I did not know if this email group accepted attachments so I have posted my two screenshots at the following URL.

In the first shot there is an irregular blue shape along the left edge with a hard to see black arrow (sometimes it is barely there, see screenshot 2). The shape changes and the arrow moves but I do not know how to interpret the information they are delivering.
In the second screen shot there is a series of 4 numbers in black lined up in front of the glider. They come and go and change value. No idea what they are indicating.
Finally, I do not see an indicator for the wind direction and velocity even though in the setup it is indicated it should be shown on the map.

Sorry for all the low level questions but I like the software and want to take advantage of all of the features that are relevant to my level of competence.
