Customizing the Multi Pens Trend

You can customize the display of the Multi Pens Trend in runtime using the Options tab.

1. The Formatting options are disabled.

2. The Fixed Time setting can toggle between the Fixed Time Mode (when selected) and Moving Mode (when not selected). When the Fixed Time checkbox is selected the trend area will display trend data for a specific duration, and will not move.

3. Select the Time Interval from the list of predefined options in the drop down list. The time interval selected here will be set as the initial value in runtime.

4. Select where in the Trend Area the Scale Label should be displayed; On the left, right, on both sides or display no scale label.

5. Click Trend Data Shown on Click to customize the behavior of the cursor readout dialog in runtime.

   By default, the Cursor Readout dialog will be displayed when cursor hovers over the Trend Area. When this option is selected, you can show and hide the Cursor Readout dialog by clicking in the Trend Area.

6. To hide the top header, select Hide Top Header. Only the trend area and toolbar will be displayed.

7. Select the required color for grid lines using the Grid Line Color option.

8. Select a pre-defined style from the Element Style drop down list.

9. You can also choose a color for the background using the Background Color option.

10. Under the Default Trend Source, select Historian or InTouch Log History/LGH for the Source field.

    By default, Historian source and Auto Detect options will be selected. When Auto Detect is checked, the Server Name will be disabled.

    When an expression or reference is entered in the Server Name field, the Multi Pens Trend connects to the specified Historian Server. The button to the left of the Server Name field toggles input to the field as an expression or Static Text mode.

    The Historian server is automatically detected from the AppEngine on which the reference attribute is running. For example, if the Reference field is set to UDO.UDA1, Auto Detect is set to the Historian server name configured for the AppEngine on which UDO is running. Auto Detect is only valid for Application Server References. A Trend Pen only shows live data if the Server Name field is left blank in Expression mode.

11. If you select InTouch Log History/LGH, use the button next to the UNC Path field to toggle input to the field as an Expression or Static text.

    1. If you select the Expression mode, you can click the ellipsis button to launch your HMI's attribute/tag browser and select a Custom property, attribute or tag.

    2. If you select the Static Text mode, you can click the ellipsis button to launch the file browser where you can specify the LGH file location.
