Process Graph

The Process Graph screen for a variable can be displayed by pressing the "GRAPH" button on the Process Table screen. The variable name and the units of measurement are displayed at the top of the graph. The high and low limits as defined for the job are indicated on the left side.

The x-axis is the cycle number. The y-axis is the actual process variable value. The graph can display the last fifty values with the rightmost point being the most recent value. For each machine cycle update, the new value enters from the right and moves the older values to the left. An undefined value will be a blank space in the graph.

If SPC data is available, a navigation button will be shown to display the SPC graph as shown in the screenshot. The Process Select button will return you to the selection screen.
