Help setting up Line Graph for multiple years
I have a database where I am making a count of "requests" seperated by weekending date. I have been doing this since mid 2011. I would like to compare the trend line, each line representing 1 year, of the # of "requests" by week ending date.
So, I have been able to do this for a year at a time, but when I format the chart I am not sure how to set up the paramaters for the X axis to show 1 year and the Y axis to show a number range (number of requests). I assume I would need 3 Y axis for each year?
Please help. Obviously I am a novice so let me know if I left out any key details.
