The auto correlate the graphs in LoadRunner analysis is done to find the root cause of the application under test issues. When the auto correlation is done, the graphs are compared and their degree of relationships between the graphs are computed. Using these related graphs, a load test engineer can analyze the graphs and give the reasons for the bottlenecks.

To auto correlate the graphs in LoadRunner analysis is done with the below mentioned steps:

1. Open the LoadRunner Analysis
2. Select a graph
3. Choose the menu options **View > Auto Correlate Graphs**
4. The Correlate Graphs dialog box opens
5. Select **a measurement** to correlate with which you want to auto correlate your active graph. Only the graphs with a common x-axis to the active graph are available.
6. Select the **time range** for auto correlation
7. Select the **correlation options**, and choose which are the other graphs that you want to correlate with.
8. Click **OK**.
