Historic charts allow for more customization then the default Location and Parameter charts available in Chart View. You can create multiple y-axes with fixed or automatic scaling, change the data aggregation and styles of individual parameters and preset the default time range.
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.
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 X-axis and Y-axes of the chart.
Set the position of the x-axis (time) to display on the Top or Bottom of the chart.
You can create unlimited y-axes to be displayed on the chart.
Click the Edit button to show and modify the configuration for each y-axes. Use the Add Y axis button to create a new axis. Axes can be removed via the dropdown menu (accessible by clicking the menu button on the top-right corner of the axis item).
Y-axes can be linear with automatic or fixed minimum and maximum ranges or displayed with logarithmic scaling.
Drag and drop axes in the list to change their display order on the chart.
By default, links are automatically assigned to the first y-axis. You need to Edit each link and specify a Y axis.
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.
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.
