Group Bar Graph - Showing number of occurence

So in my data, I have credits, revenue, & credits with revenue at different discount levels. These data show the average revenue that I made at different discount levels. I had a promotion where 5% discount was used 10 times, 10% used 20 times, 15% used 3 times through a year. How do I show on the bar graph the number of times I used that discount level with my average revenue & credits. Let me know if you need more clarification. 

Thanks!
