Threshold value

In the Graph display area, set a level as a reference to draw a reference line.
Select "Graph" > "Threshold value" from the Menu, display/hide of the threshold value can be set, and the threshold value can be changed by Graph set.
When both points and threshold values are displayed together on the same graph, points are depicted as "Red Triangle" with data values higher than threshold values and they are depicted as "Blue Circle" with data values below the threshold values. When threshold values are displayed in the bar graph, points higher than the threshold values are drawn with a red curve and points lower than the threshold values are drawn with a blue curve, so that an easy-to-see graph can be created.

Note: "Display/Hide"' of threshold values is applied to all of the Graph windows. Threshold values can be set for every Graph window.
