I would like to graph my data from a shapefile. The data I wish to display is the sum of the nominal data per each year that it occurred.
I have enclosed a screen shot of what I mean. In red, is the column of data I wish to graph. I want the W's totaled per year and the A's totaled per year. Then I can display those bars on a yearly basis with their respective totals. If that makes sense, please help me. Thank you.
