Group quick measure output

Hello,

I have created a quick measure to subtract a single column from another for 10,000+ data lines. The result is that I have 10,000+ different results (decimal no.) and am struggling to present this graphically. 

Ideally I would like to show the number of lines in range bands, i.e. 0-5, 6-10 etc. 

Where do I start please?

Thank you,

Simon
