Deleting overlapping lines in a plot
显示 更早的评论
Hi all,
I have a .fig file that is made up of red and black lines and I want to be able to export this as .pdf. Plot twist: Each of the red lines shown here has an underlying black line that I want to just get rid of, so it results in only purely-black and purely-red lines. Any idea how to solve this?
Thanks!

Do you have a source where those curves come from? A script?

.fig files retain Children information of the figure; you can loop over the Children and delete based on color.

hf = figure(1); clf, hold on
%% Make a two color plot
for ii = 1:20
vX = [rand, rand];
vY = [rand, rand];
if (rand > 0.5)
plot(vX, vY, 'r')
else
plot(vX, vY, 'k')
end
end
%% remove black things
curAxes = get(hf, 'Children');
for curChild = get(curAxes, 'Children')'
if (isequal(curChild.Color, [0 0 0])) % black lines
delete(curChild)
end
end
Also check that you are looking ato two things - ie the red and black are different lines. There are multiple color properties with some plotted things; 'color', 'MarkerEdgeColor' ,'MarkerFaceColor' make sure the line you are looking at is not two colors simultaneously.

You will need to then loop over all combinations of red and black lines testing for pairs.
The pair test: If the end points of the overlapping lines are coincident you can do a distance test on each end. Else you can try using polyfit to determine if the two lines have the same slope and y-intercept.
Or if you have a small number of plots and lines you can loop over each black line, make the line a new color and used input() to specify if that line should be deleted; if not restore its color
