Load runner Analysis Granularity issue - Reduce for all Graphs is not working

If you wish to use a greater level of granularity for a large number of graphs, use the following settings:
1. Open the "Tools > Options > Result Collection" tab before loading the result (before starting a new session).
2. Choose "Data Aggregation > Apply user-defined aggregation" from the drop-down menu.
3. Select "Aggregation Configuration" from the drop-down menu. There, in the field "Select the granularity you wish to utilise," type the number you require.After that, you can use the option to reduce the granularity of several graphs.
