Drawing a histogram with large data

Hi everybody,

For better explanation of question, please take a look at the attached sample. I would like to draw a histogram of count of case (y axis) vs length (x axis).
Actually, I would like to show the count of cases that their lengths are 200-400, 401-600, 601-800, 801-1000, 1001-1200, 1201-1400, > 1400.
(the number near the word of case is not matter. As I explained, the counts of cases that have length say 200-400 is my interest).

It's obvious that these number located on x axis. However, I don't know how I can to show this distribution. Could you please help me out on this issue?


Thanks so much in advance and looking forward to hearing from you.
