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.
Configure properties via the Workspaces Tree’ context menu. Requires configure permission.
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:
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.
Optionally enter a description to be displayed on the chart below the title.
The Axes section allows you to customize the style and functionality of the chart axes.
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).
Use the style section to change the appearance of the chart series. Refer to parameter chart configuration for a description of all available settings.
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.
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.
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.
Enabling public access allows anyone to view the node (attachment, chart, dash or historic data) using the generated URL.
You can also embed charts and dashboards into your own website with basic HTML. Select Copy embed HTML from the URL dropdown menu for a generic code snippet (you will need to paste this in to your website).
Use the available options to customize the URL based on your display preferences. These options are transient and you can use multiple variations of the URL at the same time.
If you disable and re-enable the public access feature a new url will be generated and the old url will no longer work. This feature is NOT available on Starter accounts.
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.
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.
