Integrity Monitor Displacement Chart view

The Integrity Monitor Displacement Chart view displays the position estimates of the parent module after adjustment in a graphic. All displayed data refers to the point or station selected from the selection field at the top. All times shown here are in the time system you have selected for the Trimble 4D Control Server system.

All charts show the same general behavior. They have a common set of chart options you can modify; you can switch data sets on and off as desired, you can zoom into them, you can save their contents to graphic or data files, and you can print them. For a detailed description of how to get the best out of the chart views see the Chart Views section of this Help.

Point/Station selection field

Select the point or station to which the curves refer to. Fixed points and stations are not available for selection.

Note - The Displacement Chart view creates one chart for a point, regardless of the number of total stations measuring that point.

The diagram

The diagram displays for the selected point/station the coordinate displacements in each direction (D North, D East, and D Height), in plane (D 2D), or three-dimensionally (D 3D) in form of a line graph with the horizontal axis as time and the vertical axis as the displacement. If GNSS data contribute to the network, vertical bars can additionally indicate the minimum and the maximum value of the data that contributed to the mean value of each data point.

If linear trend lines are displayed you can see the velocity of the point/station in the corresponding direction in the legend of the diagram. The unit of the velocity depends on the time range (which you can select either using the chart property or by zooming) displayed in the chart.

For GNSS data, the Integrity Monitor module reduces data depending on the selected Time span setting in the Chart Data Properties:

• For periods up to 24 hours the data is not reduced, the data set as received from the parent module is displayed.
• For periods between 1 day and 1 week, the data is reduced to one data sample per minute.
• For periods of more than 7 days, the data is reduced to one sample per hour.

Integrity Monitor Displacement Chart Properties

For the Integrity Monitor displacement chart additional properties exist.

The chart Properties appear if you right-click into the graphic of any module and select Properties. One of the following happens:

• The Properties view appears.
• The settings of this dialog appear in the Properties view, if the Properties view is already visible (either docked to the main window or floating).

Use the Monitor Displacement Chart Properties category to view and edit settings specifically applying to the Integrity Monitor Displacement Chart view.

Show 3-s lines: If set to Yes, the matching 3-s standard deviation lines display for the currently selected displacements. Both, the positive and the negative values appear above and below the zero line. The lines appear in the same, but lighter color as the measurements they refer to. You can easily toggle this setting using the button at the top of the chart.

Show alarm lines: If set to Yes, the positive and negative values of the alarm thresholds for the three-dimensional displacement display as yellow (warning) and red (alert) dashed lines above and below the zero line. You can easily toggle this setting using the button at the top of the chart.

Show linear trend: If set to Yes, linear trend lines are calculated using a linear regression. The computation takes all measurements into account which were made in the displayed time span (that is the time span you have selected using the chart properties or by zooming into the view). You can easily toggle this setting using the button at the top of the chart.
