Building a chart from call log data

Building a chart from call log data

I have a table full of call logs and  I need to build a graph that groups the logs entries that occur between each hour of the day and then count that number.    The question I'm trying to answer is the average number of calls per hour for a given time frame in order to find the hours that are the busiest for our help desk in order to justify additional help during these hours.   I'm fairly new to this so forgive me for asking a question that most likely has a simple solution.
