Does pcolor support datetime?

Does pcolor support datetime axes? When I call pcolor with a datetime vector it produces the error "Data inputs must be real."

In my understanding, you would like to have date formatted tick labels for axes when using 'pcolor'. You cannot directly provide 'pcolor' with datetime vectors as of now.

However, there is a way to use the ' datenum ' and ' datetick ' functions to get datetime axes tick labels as illustrated in the example below:

%Creating two example vectors of datetimes, tx and ty
t1 = datetime(2017,9,2,0,0,0);
t2 = datetime(2017,9,30,0,0,0);
tx = t1:5:t2;
ty = tx + day(15);

%Creating an example C matrix for pcolor plot
C = magic(length(tx));

% Using datenum to convert to real numbers for plotting and dateticks for
% date labelling. You can play around with datetick options to suit your needs 
pcolor(datenum(tx), datenum(ty), C);
datetick('y', 'dd-mm-yy',  'keepticks');
datetick('x', 'dd-mm-yy',  'keepticks');

I hope this accomplishes what you would like to do.
