I came across this thread and saw something similar to what I am experiencing, I have a list that has over 2,783 items, I wanted to run some testing to make sure the chart was going to pull the data correctly so I put a "1" in each line and then let it sum, on the chart I am seeing only 2000 items though. I changed the "Query All Fields" in the configuration section to each option "Default, On, Off, Explicit" however none of them showed more than the 2,000 limit. Can someone explain this to me? This list is going to go over 20,000 items and our server threshold is set to 5,000.
