I need to make a comparison of months by day using a line chart. The user should be able to click on the yearmonth field to pick the months that they want to compare. (each year-month will be a different line)
The x-axis will contain day numbers i.e., 1 to 31.
The y-axis will contain sales (cumulative daily so on day 1 it will show amount of sales made on day 1 of each month selected, on day 2 it will show the sales for day 1 + sales for day 2 for each month selected, etc)
