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.

Very useful, thanks. The help suggests using AXIS(AXIS) to fix the limits, I think the same effect can be acheived with AXIS MANUAL, which would be clearer.
It's also not obvious that the arrow will be a patch object, so has properties like edgecolor, facecolor, rather than line properties.

Perfect!
