I am trying to create a histogram from a data set in excel by importing it to matlab.
I can't get the histogram function to work with a table or data array after import.
I need to use the data set to make a histogram with a bin width of 50 and then subtract one entry per bin.
how do I reference the array or table in the histogram function? how would I subtract one entry per bin?
any help would be greatly appreciated.

I was able to figure out the histogram part by importing the intire .xlsx file with
[num,~,~]=xlsread('histogram2.xlsx');
d=num;
histogram(d,50)
histfit(d,50)
here is a small portion of the full data set:
1756
1055
4193
1156
7285
1095
845
3088

To decrease, one entry per bin, try this
[num,~,~]=xlsread('histogram2.xlsx');
d=num;
h = histogram(d,50);
h.BinCounts = h.BinCounts-1
