The Trend Viewer
The trend’s thresholds are only informational and thus are not the same as the
tag’s thresholds.
Figure 38. Trend Properties, Thresholds Tab
Following is an explanation of the options on the Thresholds tab shown in
Figure 38.
•In the Thresholds list, use the Add, Remove, Move Up, and Move Down
buttons the same way you use them for Tags. In this case, however, when
you Add a threshold, you will give it a name that has meaning for you.
• General
• Name the threshold you added. If you don’t enter a name,
addVANTAGE names it something like
Threshold 1.
•Enter a Value that determines where the threshold starts.
•Use the Label Color chooser to pick the color of the name or value of
the threshold displayed in the trend.
• Select the Show name on y-axis checkbox to display the Name of the
threshold on the grid, in the color you chose. If you do not select this
checkbox, the Value will be displayed instead.
• When you select the Always show thresholds checkbox, the threshold
always displays on the grid, no matter which sensor is selected in the
Legend. When this checkbox is not selected, the threshold displays on
the grid only when the corresponding tag is selected in the Legend.
•Use the Fill fields to determine an area that should be filled (Fill to) from
the entered Value to a Base set in the next field. You can also select Min.
Scale or Max. Scale to draw a fill box in the range between the Value and
the bottom or top of the plot.
•Use the Line fields to determine whether to Paint (draw) a line and which
color to use, as well as which line Weight (thickness) to use.
