You can view the pattern of a line graph more effectively by standardizing the graph's y-axis values. Standardizing a graph causes the graph's y-axis values to converge around zero. This cancels the measurements' actual values and allows you to focus on the behavior pattern of the graph during the course of the load test scenario.
Analysis standardizes the y-axis values in a graph according to the following formula:
New Y value = (Previous Y Value - Average of previous values) / STD of previous values
