Note: Tags drawn using the Plot Data drawing method must have an associated logger tag recording their data. Information on logger tags can be found in Logger Tags.

The Tag field displays the name and description of the tag that is currently associated with this drawing method.  You can use this to select a different tag or parameter to use as the data source for this drawing method.

The Tag field is only present when editing a completed drawing method object

The Display Last field and drop-down list are used to configure the time span to be displayed in the completed Plot Data object.

You may select Minutes, Hours, or Days from the drop-down list, and enter a corresponding number in the field to its left.

Select this option if you wish to display incremental units of time along the bottom of the completed Plot Data object.

Select this option if you wish to display the alarm setpoints (if any), that associated with the tag being drawn on the completed Plot Data object. Alarm setpoints will be drawn as horizontal lines at the values matching the setpoints.  This checkbox will not be enabled if the tag has no associated alarms.

The Value to Output drop-down list enables you to select a value associated with the tag being drawn to plot. For the majority of tags, there will only be one default option, "Value", indicating the value of the tag.

Selected this option if you wish to use the Scaled Process Data Min and Scaled Process Data Max properties configured for the tag being drawn.  This will be the most common case.

If plotting a tag such as a Calculation, that does not have scaled process values, you can uncheck this box in order to provide the minimum and maximum values expected.

These fields adjust the minimum and maximum values shown on the graph’s vertical axis. They have no effect on the tag’s value, which is  what will be plotted.

Select if you wish the minimum and maximum scaling values to be displayed to the left of the completed Plot Data object.  Without these values displayed, it can be difficult to judge the meaning of the plotted data.

Opens the Select Color dialog from which you can select the color with which this tag's data will be plotted on the completed object.  You should select a color that provides a good contrast from the background.

Opens the Select Color dialog from which you can select the color with which the grid will be drawn on the completed object.  You should select a color that provides only a slight contrast from the background so as to not obscure the plot line.
