The Edit>Options>Line Width… command does not change the width of existing lines. Use Roi.setStrokeWidth(w) instead of run("Line Width...", "line="+w).
-wayne
run("Dot Blot (7K)");
run("Line Width...", "line=1");
makeLine(482,48,387,125,246,90,156,175,67,143,54,223);
roiManager("Add");
for (i=1; i<33; i=i+10) {
roiManager("Select", 0);
Roi.setStrokeWidth(i);
run("Line to Area");
roiManager("Add");
}
roiManager("Show All");
