In cloudwatch dashboards how can I get the number widget to update correctly while I change the time range on the top?

In cloudwatch dashboard, we can select the time range from the top where it's also possible to select a custom time range so is it possible for us to show the aggregate results in the number widget which has been created. Here, the period was selected to be 1 day and after that, if we select the time range to be anything beyond 1 day (say 3 days, 1 week, 1 month, etc.), we will not be able to see the accurate data as we can't see aggregate values for time range more than 1 day. Is there any way we can fix this so that it shows the correct data?
