Chris, You could try the SplitLineOnDistance command in your DrawGraphics to eliminate these 'jump lines'. That might work if they are all long straight segments and the rest of the curves are defined by closer points. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Chris Chiasson [mailto:chris at chiasson.name] To: mathgroup at smc.vnet.net I have deleted parts of contour lines that are outside a particular domain. http://chris.chiasson.name/temp/fix_bad_contours.png The problem is, since some of the lines begin and end inside the allowed domain, I end up with orange slice shapes as seen in the top two contours of the picture. What is the best way to detect this and reorder the points in the line directives so that they only follow the real contours? The main reason I am not just coloring over the contour lines is that David Park's label drawing function will only put labels in the correct spot if the labeled Lines contain only the segments that will be visible. If I don't delete the parts that would be covered up, the line labels will print in the invalid domain. -- http://chris.chiasson.name/
