The recent statistics is always displayed on the rightmost pane for each data series. Data is captured periodically in regular intervals on the ASMM server. Each graph is a view that continuously rolls to present near real-time data. You are presented with a graphical view of the statistics on the browser based on the selected category of activities. Each presented graph contains a fixed number of data points based on the selected time periods.
