With a load testing tool, you want to discover a system’s performance and better ways to improve it. While doing that, you make some observations and record your findings. Now, you can plot graphs using the data you have. Two types of graphs can be plotted – Correlate Graph and Overlay Graph.
The Correlate Graph involves plotting the Y-axis of two graphs against each other, whereby the Y-axis is for an active graph while the X-axis is for a merged graph. On the other hand, the Overlay Graph has two graphs sharing a common X-axis, where the active graph has the left Y-axis, and the right Y-axis has the merged graph.
