23 Sep 2009	Google Earth Toolbox Various plotting/drawing functions that can be saved as KML output, and loaded in Google Earth Author: Scott L. Davis	Great job, although there are a couple of problems I'm having with the 'ge_contourf' function. I'd like to plot just 1 contour on GE and here's my test script: _____________________ close all clear all [X,Y] = meshgrid(1:20,1:20); Z = peaks(20); cMap = 'jet'; lineValues = [ 0 0 ] ; [C,h] = contourf(X,Y,Z, lineValues); colorbar axis image colormap(cMap) kmlStr = ge_contourf(X,Y,Z,'cMap',cMap,... 'polyAlpha','7F', 'lineValues', lineValues); ge_output('test_contourf.kml',kmlStr); ___________ The script as run above produces an error in the "isinner" function. I was able to tweak this by making 'firsttest' have a single scalar value so it'll accept the && test at the end of the function. This tweak actually gets the ge_contourf function to run but the other problem is that the resulting contour, and the polygon created in the .kml file, is the reverse of what I actually want and the reverse of what the CONTOURF function produces. If you change the lineValues parameter to "[ 2 2]" then the resulting .kml polygon matches that produced by CONTOURF. Although I'd still like only 1 color showing on GE and not the background color - that is, I'd like 1 colored contour showing on GE. Any ideas on how to tweak the ge_contourf function so I can get it correctly create the polygon and .kml file when the polgyon goes to the outer edges of the 'box' (i.e., the example when lineValues = [0 0])?
