A control chart is primarily used to monitor the variability of a process over time and displays statistical data to help identify trends, shifts, or any unusual variations in the process. While it does visually represent data points in relation to control limits, it does not represent "various states" of the process itself in a comprehensive way. Instead, it focuses on the performance of the process concerning its defined parameters and variations.

The nature of control charts is that they provide a means of distinguishing between common cause variation—which is inherent in a process—and special cause variation, which indicates a problem that needs to be addressed. This function makes them crucial for process improvement and quality assurance in various fields.

In contrast, the idea of depicting "various states" might be interpreted more broadly and not accurately reflect the specific, focused purpose of a control chart within the broader context of process management and quality control. Therefore, the statement regarding control charts does not fully encapsulate their function, leading to the conclusion that it is false.
