I have a large line graph tracking my finances. Points are a weekly total, and because it is now at about 750 points I have formatted the X-axis to show by month. To compensate for the density of this graph, I use the mouse hover to inspect a point for its value. The Y-axis is good. However, the date indicated when I hover is not the actual date of a particular amount. It seems to be a date derived from the X-axis. An example:
Date Amount
2/5/21 627680
2/12/21 635750
2/19/21 640874
2/25/21 635324
Hovering over each of these points shows the date to be Feb-21 [the format of the X-axis] rather than 2-12-21 which is available in the data set.
