Plotting negative values on an histogram

I am plotting some values on an histogram.
figure
histogram('Categories',Categories,'BinCounts',[-72 -63 -54 -56],'BarWidth',0.5,'FaceColor','#EDB120')
xlabel('Membrane potential');
ylabel('Rest Memb Pot (mV)');
title('Amplitude of AP');
The problem is that whenever one of the values for BinCounts is negative, I get this error:
Error using histogram (line 156)
Expected input number 4, BinCounts, to be nonnegative.
While everything works perfectly if the values are all positive.

Or maybe that's the data??? It doesn't make sense to have a negative count. If you want bars that go negative, use bar() not histogram().

It seems likely that you've mixed up BinCounts and BinEdges - it doesn't make much sense to have a negative number of something in a bin (perhaps in economics if we're talking about debts?).
