How can I create a widget that shows requests opened last 24 hours

How can I create a widget that shows requests opened last 24 hours

Hi Support, I am trying to create a widget in the ME ServiceDesk Plus Analytics area for a daily ticket counter widget per the instructions in this video. Somehow It won't let me create the 24 hour window. I just want to know how many tickets were entered in the last 24 hour window, please? Can you show me with a video like this, please?
