Graph by Hour Unavailable on Date Selector
I have a bar chart where the X Axis is a datetime beast mode created using the str_to_date() function and I am charting by hour. In design of the card I can set any date range and the card graphs by hour. When viewing the card if I change the date range the card defaults to a Graph By of Day and greys out Hour. Why am I losing the graph by hour functionality?
Thank you in advance for your assistance.
