Displacement

Displacement charts allow you to visualize vertical or horizontal measurement displacement over time. Typically, instruments that require displacement charts are on a string along a line, either down a borehole, along a structure or underneath embankments.

Properties

icon-properties Configure properties via the Workspaces Tree’ context menu. Requires configure permission.


General

The General section allows a default Start range and End range to be set. This range will be used when the chart is initially displayed. Choose a preset or Custom OPC for relative time. Select Custom Fixed for absolute time. The None option can be used to read forward or back through the time series data until the Maximum series limit is reached.

You can customize the chart with a number of other general settings:

../../../../_images/chart_displacement_general.jpg

Profile orientation
Vertical displays depth on Y-Axis and measurement on X-Axis. Horizontal displays distance on X-Axis and measurement on Y-Axis.
Maximum series
The maximum number of series to display on the chart (between 1 and 15).
Series time format
Select a preset display format from the drop down list or specify a custom format using time format tokens.
Measurement baseline

Absolute: Measurements are not modified.

Relative to first value in range: Measurements from first series in requested range are subtracted from all subsequent series.

Relative to first recorded value: Measurements from first series in parameter history are subtracted from all subsquent series.

Relative to fixed time: Measurements from series at a user-defined time are subtracted from all subsquent series. Select the time from the control below this option.

Measurement process
Processing to apply to all measurement values. Raw will not apply any processing. Sum from Start and Sum from End will totalise measurement values.
Measurement offset
Numeric value to add/subtract from each measurement value.
Measurement units
Suffix to display with measurement values.
Depth/Distance units
Suffix to display with the depth/distance values.

Optionally enter a description to be displayed on the chart below the title.

Axes

The Axes section allows you to customize the style and functionality of the chart axes.

../../../../_images/chart_displacement_axes.jpg


Thresholds

Threshold lines and bands can be added to the chart and displayed either horizontally or vertically. The threshold value for a line will determine where the line is placed on the axis. The threshold start and threshold end values for a band will determine the band position on the axis.

Drag and drop thresholds in the list to change their display order on the chart. Thresholds can be removed via the dropdown menu (accessible by clicking the menu button on the top-right corner of the threshold item).

Style

Use the style section to change the appearance of the chart series. Refer to parameter chart configuration for a description of all available settings.

Data

Use the data section to set the aggregation mode for time series data to be displayed on the chart. The aggregation mode applies to the measurement data, while the aggregation period applies to the time ranges. Refer to parameter chart configuration for a description of all available aggregation settings.

../../../../_images/chart_displacement_data.jpg

Automatic
Automatic allows the chart to determine the most suitable period based on the chart range.
Custom
Custom requires the choice of aggregate type (which will be applied to the measurement data) and period interval (which will determine the timestamp of each series).
Raw
Raw uses the timestamps and measurements of the records directly as the series represented on the chart. However, as the maximum number of series that can be displayed on a chart is 15, while a typical data file could contain hundreds or thousands of individual timestamped records, some form of aggregation is generally recommended.

Security

The Security section displays a list of all users and groups that have access to the Node. Users with security permission can restrict user and group access to the node and its descendants by assign the No Access role.

New users and groups must be added via the Workspace Security section.

Note

The Account Owner, Administrators or Workspace users/groups that have been assigned a Workspace role with the configure permission can not be assigned the No Access role.


Copy/Paste Charts

icon-paste Copy/Paste operations can be performed from the Workspaces Tree to quickly duplicate one or more charts. Links are automatically re-assigned to corresponding Nodes relative to the Chart if they exist at the destination. ie. You can copy/paste complete Locations containing charts without manually re-assigning all links.

Move Charts

icon-move Moving a chart within a Workspace will keep existing links. Moving a chart between Workspaces will invalidate any Link where the linked node is not available in the destination Workspace.
