A VERY useful function. However, I get slight offsets in the vertical locations of the lines/markers in different columns. Have you seen this?

For example, the code:

nrows = 1;
ncols = 3;
n = nrows * ncols;
x = repmat([0;1], 1, n);
y = [zeros(1,n); (1:n)/n];
h = plot(x, y);
strs = num2cell(char('`'+(1:n)), 1)';
[legax,legh] = legendflex(h, strs, 'ncol', ncols);

get(findobj(legh,'type','line','LineStyle','-'),{'YData'});
cat(1,ans{:}); yline=reshape(ans(:,1),[],3)
get(findobj(legh,'type','line','LineStyle','none'),{'YData'});
cat(1,ans{:}); ymarker=reshape(ans(:,1),[],3)
get(findobj(legh,'type','text'),{'Position'});
cat(1,ans{:}); ytext=reshape(ans(:,2),[],3)

gives the results:

yline = [9.5388 9.2710 9.0032]
ymarker = [9.5388 9.2710 9.0032]
ytext = [4.3091 4.3091 4.3091]

showing that the text items are set at consistent locations, but the lines and markers are slightly offset. (Change nrows to, say, 8 and the same vertical offset happens on all elements of subsequent columns.)

Any suggestions?

P.S. This is in MATLAB 7.14.0.739 (R2012a) on a Mac.

Perfect!

I wrote the following code:

figure(1)
clf
hold on;
scatter3(X,Y,Z,'ko')
Z1 = 500;
arrow([max(X) max(Y) Z1],[min(X) min(Y) Z1],15,'BaseAngle',60, 'FaceColor',[0 1 0])

I want to make outputs (which must contain the line along with arrow head) in X-Z plane; i.e. view([180 0]), not in 3D which is good for visualization only. Unfortunately, though the line is visible, the arrow head is not seen when I go into 2D view. I tried to include 'CrossDir',[0 0 1] as suggested by the author of the script, but it didn't help. Any suggestion?
