The default view in Live View will show up to the 50 latest Events sent into your Mixpanel project. When you apply an Event or Property filter, Mixpanel looks through the latest 100,000 Events and returns up to the latest 50 Events that match your filter criteria.
After applying an Event or Property filter, you will see a message at the bottom of the screen like this, which reflects the timestamp of the 100,000th oldest event at the time you apply the filter:
Live View is designed primarily to help review the state of the latest data as it comes in for debugging and QA purposes. At this time, there isn't a way to change the range in Live View to look at more events or a longer time period.

Data available in Live View is generally available elsewhere in Mixpanel, so you can look at other reports to see more data or a longer time period:
If you are filtering for a specific Event and want to see more historical data on that Event, select that Event in Segmentation for additional analysis.
If you are looking to study the activity of a specific user, view that user’s profile in Explore to see more data.
If you absolutely want to view the raw data coming into your project or apply more advanced filtering, please use JQL for further analysis.
