I made a two charts in 2017, one to count number of patients per month and one to count number of patients per week. These worked great in 2017, but now that it's 2018, they're not functioning properly. Specifically (looking at the monthly chart), my January 2018 numbers are being added to the January 2017 numbers and the chart isn't populating new month/years for 2018. For example, if I had 7 patients in 1/17 and 5 in 1/18, it's just showing 12 for 1/17. How can this be remedied? Thanks!
