Hi again, There are some qualifiers on the CONTOUR command that let you control some of the contour options that are otherwise given by the PPLUS command conset. See CONTOUR/SPACING under http://dunkel.pmel.noaa.gov:8980/Ferret/home/documentation/users-guide/customizing-plots/CONTOURING#_VPINDEXENTRY_860 (The label size is controled by CONTOUR/SIZE, and label significant digits by CONTOUR/SIGDIG.) The spacing is relative to some local calculations that are going on inside pplus, and so when the grid is fine sometimes the labels don't show up. Try, contour/nolab/over/lev=(0.0,7.0,0.25)(7.,9,.5)/size=0.8/spacing=1 swh_smooth and if you don't see labels, try even smaller values for /spacing. I have added some text to the section in the users guide about CONSET so that that section points to the qualifiers under CONTOUR. This documentation update will not be made public immediately but will go out the next time the users guide is published to the public web server.

So, the density of the data is much greater than original data. I read in email archive that the issue with no label at contour line occurs when data is too dense, but I reduced the density of a grid and I got no improvement. Still without contour labels. I am wondering how I can get it works? Best regards, Szymon Roziewski 2011/7/6 Ansley Manke <Ansley.B.Manke@xxxxxxxx>:Hi This is controlled by the PPLUS CONSET command. Look in the documentation and in the archives of the mail list - there have been a number of discussions of these settings. It does not have to do with how the data was derived. Did you do both plots with CONTOUR/OVERLAY? Or are they done with FILL/LINE? Ansley On 7/1/2011 5:10 AM, Szymon Roziewski wrote:Hello there, I have such a problem. I would like my contour plots to be labelled with numbers associated with its colours. I attach two pictures. The issue seems to appear when I want to draw contours of regridded data. And when I do a plot contour of raw data the problem doesn't exit. Kind regards, Szymon Roziewski |
