We show all the data points in the charts but since it can become very congested the dates are not given.
However, if this is a performance report for a network device we show each data point as a tabular column below the graph when generated from reports tab which will be helpful to see the exact data for that data point.
To access this navigate to reports tab -> search for network device -> choose performance report -> Filter according to your need.
Let us know if this works. The same can be scheduled to get the report you are looking for.
