Getting the Right Look for Your Trend Link Chart

the left side of the curve window will include a display of scale values. Otherwise, a band without numbers will appear.

Curve Type Select the type of curve: normal, highlight, shaded, or SPC (Statistical Processing Control). If you enabled the NetDAQ Logger channel alarm values, the default curve type is "highlighted" and Trend Link sets limit values according to the alarm values.

Precision refers to the number of digits appearing to the right of the decimal point (Curve Status window and Band Bars. For example, a Precision entry of 1 would show values of 70.0 and 80.0 (maximum entry is 7, showing values of 70.0000000 and 80.0000000.)

Color Click here to select the color of the curve trace.

More Button Click to open the Curve Options dialog box for the Curve Type selected.

Minimized Button Click to select display options when the dialog is minimized. A minimized dialog becomes a floating window displaying various types of information about the curve (tag name, last data value, etc.)

AutoScale Button Click to autoscale the scale values based on the current data in view in the curve window.

Draw First Button This causes the curve to be drawn on the top over all other curves.

Draw Last Button This cause the curve to be drawn on the bottom under all other curves.

Statistics Button Opens the display for the statistics of the curve, including Histogram, Box Plot, Sum, Mean, and Standard Deviation values.
