Classification: CPC G | IPC G

Claim 0:
1. An apparatus comprising:
memory;
machine readable instructions; and
processor circuitry to execute the instructions to:
generate a first graphical user interface, the first graphical user interface to include a graphical representation of a component in a process control system;
generate a second graphical user interface, the second graphical user interface to include a chart region with a first trend and a second trend represented therein, the first trend indicative of values of a first process parameter of the process control system over a period of time, the second trend indicative of values of a second process parameter of the process control system, the second process parameter different than the first process parameter; and
automatically generate the first trend in the chart region in response to a graphical element being dragged and dropped from the first graphical user interface to the second graphical user interface, the second trend included in the chart region before the graphical element is dragged from the first graphical user interface, the generation of the first trend including:
comparing a first Y-axis scale designated for the first trend to a second Y-axis scale in the chart region used for the second trend;
plotting the first trend in the chart region using the second Y-axis scale when a difference between the first Y-axis scale and the second Y-axis scale satisfies a threshold; and
adding the first Y-axis scale to the chart region and plotting the first trend in the chart region using the first Y-axis scale when the difference between the first Y-axis scale and the second Y-axis scale does not satisfy the threshold, the second Y-axis scale to be retained in the chart region when the first Y-axis scale is added.
