Hello
I am trying to draw a graph where I want to create continuous categories our of the number of days taken to release subisdy for an implement. I want to divide the categories from 0-30 days, 30-60 days, and so on. Can someone help me with generating a new variable to create categories, and count the number of implements for those categories. The data example is below:

There are few observations which go upto more than 500 days. Is there a way to include those in the graph without making it look too clumsy.
