Summarise duplicate values in a chart

Hi, 

I have an extract of employees names and  ID numbers for whenever they have received an award. I want to summarise this data so that the X axis would show the different no. of times employees have been awarded, and Y  axis showing the number of employees who have been awarded that number of times.

I have got to the stage where I have a table showing how many times each employee has been awarded, but how do I get to the next stage where I can summarise this information so can display on a chart.

e.g. 

X axis 1,2,3,4,5 (times an employee has been awarded)

Y axis ...... (no. of times e.g. that employees have been awarded 1, 2 or 3 awards etc.)

Thanks!
