Generating "Users vs Load Time Average" report requires the following specific actions:
- Using the JMeter Console, add a "Config Element -> User Defined Variables" .
- Add a variable named: "in". This variable's value should be the following: "${__P(InstanceID)}".

These actions allow the identification of each individual JMeterEngine. If these actions are not performed the graph will show the maximum users per one JMeterEngine. For example, assuming there are 4 JMeterEngines, each running 50 users. Without these specific actions, the maximum number of users will show 50. With these actions performed, the maximum number of users will reach 200.
