The Name property specifies the unique identifier for this control. Valid characters are A-Z, 0-9, and underscore (_). Spaces are not allowed. Names cannot start with a number. The default value is the object name and the numeric instance. The control's Name is also displayed on the Controls view of the Screen pane.

The read-only Type property displays the type for the control: Chart, Grid, Heat Map, Object Container, Tag Chooser, View, etc. … The control's Type is also displayed on the Controls view of the Screen pane.

The Height property specifies the height of the control (or screen).

The Horizontal resize mode property specifies whether and how the control dynamically moves or resizes horizontally when the screen is resized in run mode. Options include:

• None — No resizing occurs.
• Shift — The object will shift horizontally.
• Expand — The object will expand or shrink horizontally the same number of pixels as the screen.
• Proportional — The object expands or shrinks proportionally to the screen.

The default value is None.

The Layer property specifies the layer for this control. Layers are used to show, hide, and edit multiple controls on one layer without affecting controls on another layer.

• Type the name of the layer into the Layer field.
• All layers are listed on the Layers pane, where you can show and hide layers for the screen in design mode and run mode.

The Vertical resize mode property specifies whether and how the control dynamically moves or resizes vertically when the screen is resized in run mode. Options include:

• None — No resizing occurs.
• Shift — The object will shift vertically.
• Expand — The object will expand or shrink vertically the same number of pixels as the screen.

The default value is None.

The Visible check box indicates whether the control is visible in run mode.

The Width property specifies the width of the control (or screen).

The X property specifies the location of the control along the horizontal axis. Use the up, down, left, and right arrow keys to nudge a control by 1 pixel. Arrow moves a control by 1 pixel. Ctrl+Arrow moves a control by 10 pixels. Ctrl+Shift+Arrow moves a control by 100 pixels.

The Y property specifies the location of the control along the vertical axis. Use the up, down, left, and right arrow keys to nudge a control by 1 pixel. Arrow moves a control by 1 pixel. Ctrl+Arrow moves a control by 10 pixels. Ctrl+Shift+Arrow moves a control by 100 pixels.

The Auto range x-axis check box indicates whether the sparkline's x-axis is constrained to the range of values for the associated point or fixed to the configured time range (default). Configure the date and time range in the Range properties below.

The Auto range y-axis check box indicates whether the sparkline's y-axis is constrained to the range of values for the associated points (default) or fixed to the configured minimum and maximum values. Configure the y-axis scale in the Maximum Y value and Minimum Y value below.

The Background color property specifies the background color of the screen, object, or control. Click to select a color using the color picker.

The Maximum Y value property specifies the maximum value to use on the sparkline's y-axis when the Auto range - y-axis property is set to fixed (disabled).

The Minimum Y value property specifies the minimum value to use on the sparkline's y-axis when the Auto range - y-axis property is set to fixed (disabled).

The Date range configuration property is used to configure the range of dates to be trended in the chart or sparkline, whether to enable live data updates, the live update rate, the starting time for a trend, whether to use relative or absolute dates, and the actual date range. Click to open the Configure Time Range dialog box, where you can configure these properties.

You can change the date and time range settings for any chart in run mode via an icon on the chart toolbar.

The Enable live updates check box indicates whether this chart or sparkline will request new data at a specified interval allowing the chart to trend data at a real-time pace. When live updates are enabled and the next poll occurs, the series line will update to reflect the slope change, if any. The interval at which the trend moves forward is defined in the Update rate. If disabled, a trend is populated once with data from the Value History Service (VHS). You can disable/enable live updates for any chart in run mode via an icon on the chart toolbar.

The Update rate property specifies the number of milliseconds to wait before an auto-updated trend refreshes. The default rate is 200 milliseconds.

The Earliest (span) property specifies the starting date for a trend; that is, the amount of time in the past from when to start the trend. Enter a number in the text box and select a time period from the drop-down menu. For example, 8 Hours ago or 2 Days ago.

The Earliest (unit) property specifies the unit of time in the past from when to start the trend. After entering a number in the text box, select a time period from the drop-down menu. The options include: Seconds, Minutes, Hours, Days, and Years. For example, 60 Seconds ago or 2 Hours ago. The default value is Hours.

The Use relative date check box indicates whether to use relative dates and time for the chart. Use the Begin/Start and End properties to specify the relative date ranges to use in the chart.

If Use relative date is unchecked all dates and time will be absolute. Use the Begin/Start and End properties to specify the absolute date ranges to use in the chart.

The Begin relative date (or Relative start date or Start) property specifies a wildcard string defining the amount of time by which to adjust the start date and time. The space-separated elements in this string must be of the form: "x-#", "x+#", or "x=#" where # is an integer and x is one of the following unit specifiers: y — Year, m — Month, d — Day, H — Hour, M — Minute, S — Second, and # is an integer. T wildcard is also supported and must be in the form: T, T+#, T-#, where T represent today at midnight, T-1 is yesterday at midnight, and T+1 is tomorrow at midnight, etc. Any integer can be used. For example, H-8 represents data from the 8 hours before the current hour, d+3 represents data 3 days after the current day, and d+2 H+1 M+30 represents data 2 days, 1 hour and 30 minutes after the current date and time. d-4 H=6 sets the relative start date and time to four days ago (d-4) at 6:00 a.m. (H=6). See Date and Time Wildcards for more information about adjusting relative time.

The End relative date (or Relative end date or End) property specifies a wildcard string defining the amount of time by which to adjust end date and time. The space-separated elements in this string must be of the form: "x-#", "x+#", or "x=#" where # is an integer and x is one of the following unit specifiers: y — Year, m — Month, d — Day, H — Hour, M — Minute, S — Second, and # is an integer. T wildcard is also supported and must be in the form: T, T+#, T-#, where T represent today at midnight, T-1 is yesterday at midnight, and T+1 is tomorrow at midnight, etc. Any integer can be used. For example, H-8 represents data from the 8 hours before the current hour, d+3 represents data 3 days after the current day, and d+2 H+1 M+30 represents data 2 days, 1 hour and 30 minutes after the current date and time. d-4 H=6 sets the relative end date and time to four days ago (d-4) at 6:00 a.m. (H=6). See Date and Time Wildcards for more information about adjusting relative time.

The Begin date (or Start or Start date) property specifies the start date and time for a control (or screen or chart or column) for an absolute date and time view window. The format is MM/DD/YYYY hh:mm:ss AM/PM. The default value is the system date and time at which the control was first added to the screen. Click to change the date using the date picker.

The Point configuration property is used to configure the CygNet point associated with the control. Click to reveal a drop-down area where you can configure the Selection mode, source Facility tag, source SiteService, source Facility, and the UDC or Long Point ID for the point. Each option is described below.

The Selection mode property is used to determine how the control will receive CygNet information from other controls. Two options are available; click the desired radio button:

• Facility tag — The Facility tag selector consists of a Source chooser and Resolve to a relative facility check box. If the Source is <Self> a Facility tag selector and relative facility options are also displayed. Facility tag is the default option.
• SiteService / Facility — The SiteService / Facility selector consists of Source and SiteService and facility choosers.

Sending and receiving facility tags

Some controls on the same screen allow for the sending of facility tag information from one control to another.

1. On the sending control configure the Facility sender mode property to send facility tag information to another control on the same screen.
2. On the receiving control configure the Selection mode property (in either CygNet connection or Point configuration section) to Facility tag and select the Facility Source to the sending control.
3. On the receiving control configure a display tag that associates to a facility property, e.g. %FacilityTag%.

The Facility tag or Facility property is where you specify the source of the facility for the control (or screen) to use. The source for the facility can be explicitly configured for this control or it can be inherited from another control on the same screen, or from the screen, or from another screen. Click to reveal the Facility tag or Facility selector. Options include:

• Source — Options include <Self>, Screen (default), or a list of Sender controls.
  • <Self> — Select <Self> to explicitly configure the facility for this control. A Facility tag or Facility selector is displayed, depending on the Selection mode:
    • Facility — The Facility property specifies the facility for which the control (or screen) is to display data. Click to select a facility using the Select Facility dialog box.
    • Facility Tag — The Facility tag property specifies the full facility tag identifier for which the control (or screen) is to display data. Click to select a facility using the Select Facility Tag dialog box.
  • Screen — Select Screen to inherit the facility from the screen for this control. By default, the sender is the Screen control if no other senders have been configured. Once Screen is selected Inherited from Screen will display for the Facility property.
  • Sender — A list of sender controls that have been configured with a facility will be displayed. Select the name of the control that will send its facility to this control. By default, the sender is the Screen control if no other senders have been configured. Once a sender control has been specified its name will display in the Source field.

• Resolve to a relative facility — The Resolve to a relative facility check box redirects the source of the facility to a relative facility, overriding the configured source facility. Once selected a list of configured Relative links is displayed. See Using Relative Facilities in Canvas for more information about configuring and scripting relative facility links.
  • Relative link — The Relative link property specifies a list of all available relative facility paths. Click to reveal a drop-down menu of all available relative facility definitions (relative links). Select a link from the list. If an order-in-type attribute is specified for the selected link, the Order in type field will display.
  • Order in type — The Order in type property specifies the attribute value used to represent the order in type (facility ordinal) if the relative facility definition is configured for one. It is possible to have multiple relative facility definition sets with the same definition name. In this case, if the specified Relative link is configured for ordinalization, then you need to configure the attribute value in the box.

The SiteService property is where you specify the source of the SiteService for the control (or screen) to use. The source for the SiteService can be explicitly configured for this control or it can be inherited from another control on the same screen, or from the screen, or from another screen. Click to reveal the SiteService selector. Options include:

• Source — Options include <Self> or Screen (default):
  • <Self> — Select <Self> to explicitly configure the SiteService for this control. A SiteService selector is displayed:
    • SiteService — The SiteService property specifies the SiteService for which the control (or screen) is to display data. Click to select a service using the Select Service dialog box.
  • Screen — Select Screen to inherit the SiteService from the screen for this control. By default, the sender is the Screen control if no other senders have been configured.

The String property specifies a generic string property that can be used when scripting this control. Type a string and reference it in your script as necessary.
