[IDV #BYI-999282]: No Labels Displayed (or very few of them)



Bonjour Michel,

We have made some improvements to our contouring algorithms lately. Please 
download and try the nightly build 
http://www.unidata.ucar.edu/downloads/idv/nightly/index.jsp.

Also try experimenting with the zoom level. Sometimes that can help improve the 
contours.

Cordialement,

Unidata IDV Support

> Bonjour,

> Unfortunately, despite having changed contour intervals, contour
> smoothing, font, size, ... I don't see any improvement in the frequency
> of label displays. Using Cressman Weighted, one label was added once,
> but one label was withdrawed twice. The best smoothing seems to be
> "none" or "Gaussian Weighted" (for the same result).
> 
> In the case of sea data (significant heights; periods, ...) in Grib
> format, I still don't have any labels displayed whichever the smoothing
> used.
