The following table lists the parameters that can be edited:

Command	Description		Default
			Value
Point	Sets the X-axis values to points. For the purposes of this graph,		0
	each sample run is considered a data point. Therefore, if 2500
	sample runs were used to generate the trend graph, then there are
	2500 data points.
	NOTE: The X-axis value for the first sample, or point, in the trend
	graph is 0, not 1. The X-axis value for the final point in the trend
	graph is N - 1, where N is the total number of points in the graph.
	•	X Min - Sets the minimum value for the X axis to the point
		number of the first sample you want to use in the plot. Default
		value is 0.
	•	X Max - Sets the maximum value for the X axis to the point
		number of the last sample you want to use in the plot. Default
		value is N - 1, where N is the total number of points in the graph.
		Therefore, if there are 2500 points, then the X Max would be
		2499.
Date Time	Sets the X-axis values to the particular GC dates and times of each		N/A
	sample runs.
	•	From - Sets the minimum value for the X axis to the date of the
		first sample you want to use in the plot.
	•	To - Sets the maximum value for the X axis to the date of the
		last sample you want to use in the plot.
	• Date Format - Options are MM-DD-YYYY or DD-MM-YYYY.

The primary Y axis is the default axis for displaying trend graphs. The secondary Y axis can be used to display a second graph whose minimum and maximum values are different than the minimum and maximum values of the first graph.
