Fourth argument, category names, must be a cell array whose length is equal to the number of bins, {0,number,integer}. Unable to create unique category names using the display format of the input argument. Specify category names or change the ''Format'' property of the input. The second argument, uniform bin size, must be a duration or calendarDuration that is a positive finite scalar, or can be one of: 'second', 'minute', 'hour', 'day', 'week', 'month', 'quarter', 'year', 'decade', or 'century'. The second argument, bin edges, must be a datetime vector with at least 2 elements. Second argument must be either a datetime vector, a scalar integer, a scalar duration or calendarDuration, a character vector, or string scalar. The second argument, bin edges, must be a sorted datetime vector that does not contain NaTs. Third argument, bin values, must be a vector whose length is equal to the number of bins, {0,number,integer}. If the third argument, bin values, is of type {0}, then all of the input data must belong to a bin. First argument must be a datetime array.
