The Name property specifies the unique identifier for this control. Valid characters are A-Z, 0-9, and underscore (_). Special characters and spaces are not permitted. Names cannot start with a number; an underscore will be prefixed if the control name starts 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: Button, Chart, CygNet Grid, Edit Box, Object Container, Search Box, Tag Chooser, 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 name of the layer to which this object is assigned. Layers can be 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 (the name can be a previously created layer or a new layer).
• All layers are listed on the Layers pane, where you can manage the layers for the screen in design mode and run mode.

The Lock property indicates whether the control is locked to the current position. A locked control cannot be moved via click and drag, or nudged with the arrow keys, or resized.

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.
• Proportional — The object expands or shrinks proportionally to 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 Background color property specifies the background color of the screen, object, or control. Click to customize the color using the color picker.

The Background color source property specifies the color source for the background color of the screen, object, or control. Two options are available:

• Auto — Overrides the background color with a theme-appropriate color (default).

  Note:    Auto is not supported as a color source in TWC screens. If a property specifies Auto for color configuration, the screen will use the <Self> color that is specified in the Canvas file during the publishing process. See Color on TWC Screens.

• <Self> — The color selected in the Background color property will be used.

The default option is Auto.

The Cell padding property specifies the size of the padding around each Heat Map cell in pixels.

The Facility sender property specifies the name of the control (or map layer) that will send its facility/facilities to this control. This property is used instead of a facility filter.

The High range color property specifies the color to be used at the high end of the value range. Click to customize the color using the color picker.

The Low range color property specifies the color to be used at the low end of the value range. Click to customize the color using the color picker.

The Row header font size property specifies the font size for the text that lies to the left of each row in the Heat Map.

The Row height property specifies the height of each Heat Map row. Only applicable if the Row sizing mode is set to Fixed.

The Row sizing mode specifies the method used to size the Heat Map row height. Options include:

• Auto — Automatically size the rows based on the height of the Heat Map.
• Fixed — Size the rows using the value specified in the row height property. If this requires more vertical space than is available, a scroll bar will be added.

The default value is Auto.

The Show cell labels check box indicates whether to display the value in each cell. Note that displaying a value may have an impact on performance.

The Show scale check box indicates whether to display the color scale beneath the Heat Map.

The Show top labels check box indicates whether to display the date and time labels along the top of the Heat Map.

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 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 date or End property specifies the end 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 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 Rollup period property works in conjunction with the Rollup unit to define the interval by which a specified Rollup type takes place. For example, if you selected Minutes from the Rollup unit drop-down menu, then typed 3 in the Rollup period field, rollups for the control would occur every three minutes. Enter only whole numbers.

By default, a rollup derives its values from raw data stored in the Value History Service (VHS). The Rollup type drop-down menu enables you to rollup data for the selected point. Using the Rollup type option might be preferable to using the data thinning option because rollup calculations performed by the VHS can provide improved performance and reduced network traffic relative to data thinning. Rollup type options are as follows:

• None
• Calculated weighted average
• Calculated mean (default)
• Calculated minimum
• Calculated maximum
• Calculated delta
• Calculated last
• Thin median
• Thin minimum / maximum
• Thin last

The Rollup unit property options define the time units by which a specified Rollup type takes place. The Rollup Unit options are as follows:

• None
• Minutes
• Hours
• Days (default)
• Seconds

For instance, if you select Minutes, rollups occur on a minute basis. The interval is further defined by the Rollup Period setting, which defines how many (in this case) minutes long a rollup period is.

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.
