This setting affects every time display in the trend.

Determines the number base (

Decimal

,

Hexadecimal

,

Octal

, or

Show exponent

) used to show numeric values on the chart.

This setting affects numbers on the y-axis, current value legend, value bar, and tooltips, and the x-axis if

XY plot

is selected. If the number of decimal places on the

Y-Axis

tab is set to anything other than zero, numbers cannot be accurately converted to octal, or hexadecimal.

Determines whether data points on the chart are connected with a line.

Determines whether the time stamps shown at the bottom of the chart on the x-axis legend include milliseconds.

Determines whether a value bar is shown on the chart. Unless your chart style is XY-Plot, you can move the value bar by clicking anywhere in the chart. When you click the chart, the value bar moves to the nearest data point. To make showing and hiding the value bar available from the context menu, click select option on the

Runtime

tab.

A value bar includes:

Sets the background color for the chart. The default color is black.

To change the color, click the color square and then select a color from the palette.

If you want the background to have a gradient look, select the

Use gradient style

check box. In this case, clicking the color square opens the

Gradient Fill

dialog box. All other background areas in the control use

FactoryTalk View

ambient color setting.

Sets the text color for the chart.

To change the color, click the color square and then select a color from the palette.

Allows you to change the type style used on the runtime chart display.

The options in this group determine which types of pen information show in a current value legend. By default, the current value legend is shown to the right of the trend chart. However, if the line legend is set to appear at the bottom of the trend chart, the current value legend is shown as part of the line legend.

Determines whether pen values show in a current value legend.

Determines whether the time when data was last collected shows above the pen values in a current value legend.

Determines whether pen icons show in a current value legend to the right of the trend chart. Pen icons indicate the last read value of each pen. Pen icons move to show the current value, even if the chart is not scrolling, so pen icons may not appear at the end of a line.

The options in this group determine which types of trend line information show in a line legend.

Determines whether to show a legend for each trend line.

Determines whether the line legend is shown to the left, or at the bottom of the chart.

Sets the maximum number of pens (from 1 through 100) to show in the line legend. This option only applies when the line legend is set to appear at the bottom of the trend chart.

Determines whether to show the minimum, and maximum values for each pen as part of the legend for each trend line.

Determines the type of pen caption that shows in the line legend.

Determines the maximum number of characters (up to 80) that can appear in the pen caption portion of the line legend.

Determines whether to continually update the chart with new data at runtime.

If you clear the

Allow Scrolling

check box, data is not plotted on the trend. Instead, the data buffer fills with trend data until the buffer limit is reached. The chart will not update until the operator toggles the scroll mode manually using the

Pause

button.

If you allow the chart to scroll and update with new data at runtime, specify a scroll mode:

Determines whether a mechanism to allow manual scrolling is shown with the chart. Use the VCR-style buttons to scroll through trend data. The buttons allow operators to scroll backward and forward through data and to toggle between pausing and resuming automatic scrolling.

Sets the number of extra data points outside the display area that are stored for the operator to view by manual scrolling. When the buffer is full, old data drops off. The buffer size is limited to 32,767 data points per pen. To set the buffer size, specify the number of extra points to retain for each pen.

Scrolling is faster when data points are held in the buffer, however, larger buffer sizes require more system resources. If you notice slow runtime chart performance, you may want to reduce the number of data points held in the buffer.
