In Google Analytics, when I use country segments, as I change the date range to have more days worth of data, the value of Transactions in the graph that appear for the selected period of time, does not keep a consistent value. It does not make any sense. For example, for for yesterday Tuesday, May 8, 2018, I found a value in the graph. Then I changed the period, to a have three months worth of data, and in the graph when I put the mouse over the date corresponding to May 8, 2018, the number of transactions was not the same anymore. I kept changing date periods and the number of transactions for May 8, 2018 kept changing. This is definitely a bug. The values stay consistent when I do not choose country segments. It looks like a Google Analytics bug when choosing country segments as filters for different periods of time. Anyone experiencing the same situation? Thanks.
I understand your concern and let me clarify few things before we jump to conclusions.
