Configure historical trend display options

You can configure the visual appearance of a historical trend.

Configure historical trend display options

1. Double-click the trend object. The Historical Trend Configuration dialog box appears.

2. Set the color options. Do the following:

   • In the Color area, select the Chart Color box to open the color palette.

   • Select a color in the palette as the background for the trend.

     White is the default background color. Any other background color increases the time needed to print a trend.

   • Select Border Color to open the color palette.

   • Select a color in the palette as the border color of the trend.

3. Set the time divisions options. Do the following:

   • In the Time Divisions area, type the number of major trend time divisions in Number of Major Div.

     The major time divisions appear on the horizontal time axis of the trend. The maximum time between major time divisions is 65536 seconds, or 18 hours, 12 minutes, 16 seconds.

   • Select the color for the major division lines.

   • From Minor Div/Major Div, type the number of minor time divisions within each major time division.

     The number of minor time divisions should be evenly divisible within a major division. For example, if the major division is set to 60 seconds, entering a value of 2 in Minor Div/Major Div sets the minor time division to 30 seconds.

   • Select the color for the minor division lines.

   • Select Top Labels or Bottom Labels to specify the placement of time labels on the trend.

   • If you are using time labels, type the number of major time division lines per time label in the Major Div/Time Label box.

   • Select the color of the time division labels.

   • Select the time units shown as the label of the major time division.

     Months (MM)	Hours (HH)
     Days (DD)	Minutes (MM)
     Years (YY)	Seconds (SS)

4. In the Value Divisions area, configure the appearance of the vertical axis of the trend.

   Value Divisions options are configured the same way as the Time Divisions options. The vertical axis specifies the range of data values that appear in the trend based upon engineering units for all tags.

5. Select OK to save your configuration changes and close the Historical Trend Configuration dialog box.
