I am trying to get a single image for each month that represents just the maximum ndvi value for every month across several years. I am using Sentinel 2 data also. I want/need 12 ndvi values per year and print it to a chart in GEE. For the moment, I have a code set up that is able to print out charts with smaller date ranges, but I need to figure out how to get a chart with 12 points across the entire collection.
Here is a code I have been editing: https://code.earthengine.google.com/54e041bd381bac1da0ae1a5bd3411183 This is one of my assests just in case: https://code.earthengine.google.com/?asset=users/jspining/Wine_Districts
