Hi Yuri,

You can try the ChowRodgers mode, which adjusts area ratios instead of absolute areas, and seems to give more satisfying results when actual solutions are impossible. Unfortunately when I tried your dataset I found a small bug in the code -- I just submitted a fix, but it will take a day or two to show up on FEX. If you want you can just fix it yourself: line 563 says:

x = NaN; y = NaN;

It should be edited to include:

x = NaN; y = NaN; sinTp = NaN; cosTp = NaN;

Then you can plot the approximate venn diagram with

venn([477 487 370 3 54 5 2], 'ErrMinMode', 'ChowRodgers')

what are the chances this could be extended to work with custom handle objects, i.e. classes that inherit from handle?

[h, s] = venn([49, 58, 108], [33, 1, 17, 0], 'ErrMinMode', 'ChowRodgers');
This will prompt errors and can't generate h and s variables.

Great job on the function. My only beef is that the zone centroids don't seem to be quite accurate.

Trying to build venn diagram with the vector v=[477 487 370 3 54 5 2];
Without any additional parameters I've got an error:
Exiting: Maximum number of function evaluations has been exceeded
         - increase MaxFunEvals option.
         Current function value: Inf
Worked only with
venn(v,'ErrMinMode','None');
but didn't get any 123 intersection. No problem with vennX, but I really like the idea of vector graphics.
I don't need exact proportions, something close would be good enough.
