Arguments for Diagram Appearance

works with the TREESPAN= argument to determine the direction of growth for the diagram. The ANGLE= argument is valid only when you do not specify the TREEDIR= argument. The TREESPAN= argument defines the angular width of the tree (narrow or wide layout). The TREESPAN angle can be visualized as a V shape, with the starting node positioned at the base of the V. The rest of the nodes are laid out between the spreading arms of the V. The ANGLE= argument specifies the angle of the V shape. By default, the value of the ANGLE= argument is zero (0) and the V shape opens to the right, as if the letter V was rotated 90 degrees clockwise, to the three-o'clock position. Values of the ANGLE= argument that are greater than zero rotate the V shape counterclockwise away from the three-o'clock position. Valid values for the ANGLE= argument range from zero (0) to 360 degrees.

specifies whether a border is drawn around the background area. The default value is N.

specifies a background color for the Treeview Applet. The value must be a valid HTML 3.2 color name.

specifies the color of the Collapse/Expand handle on the nodes. The handle is represented by a small plus sign (+) that is prefixed to the label of the node when its subtree is collapsed. The value must be a valid HTML color name.

specifies the node background color. The value must be a valid HTML color name. The value specified here can be overridden by specifying a value for the NCOLOR= argument.

specifies a color for nodes that are selected by the mouse or as the result of a node search. The value must be a valid HTML 3.2 color name.

specifies the percentage of the nodes that will be displayed with node labels. After the percentage has been reached, nodes are drawn as rectangles. The size of those rectangles decreases as the distance from the starting node increases. Valid values range from 0.0 to 1.0 (The decimal value is mapped to a percentage from 0% to 100%). The default value is 0.5. See also the DEPTH argument.

specifies a whole number greater than zero that determines the maximum number of links that are to be displayed in the node and link diagram. Paths whose lengths exceed the limit are truncated. This argument affects only the initial display of the diagram. Nodes that are initially hidden can become visible as a user selects nodes and navigates around the diagram.

specifies the HTML target or the name of the browser window or frame where drill-down URLs are displayed. The default behavior is to open a new browser window and reuse it for subsequent drill-down requests. Specifically, the default value is _BLANK, which is one of several reserved names for targets in HTML. The value can also be the name of a window or frame in the Web presentation.

specifies whether the applet will check for duplicate node IDs. The default value is FALSE. When set to TRUE, this argument will cause the applet to update an ID if a duplicate ID is found, instead of creating a new node with the same ID. This enables you to collect node information from different locations in the data set.

specifies the distortion factor for the fish-eye lens. The distortion factor determines the amount that the central region of the display is to be expanded (or zoomed). The value specified must be greater than or equal to 1.0. The default value is 1.0, which represents the lowest amount of distortion. This argument is valid only when the value of the FISHEYE= argument is Y. The maximum effective value (beyond which no further distortion is visible) is variable depending on the number of nodes in the diagram.

indicates whether the diagram is to be displayed with the fish-eye distortion, which displays the central region of the diagram at a specified size and displays the rest of the diagram as if it were mapped onto a ball, with the nodes and links disappearing over a curved horizon. The Web user can move the diagram past the central region by scrolling or searching for nodes. The amount of distortion used in the fish-eye lens is determined by the FACTOR= argument. The default value is Y.

specifies the size of the node label text font, in points. This argument is overridden by the NFNTSIZE= argument.

specifies the text font style for node labels. Valid values are BOLD, ITALIC, and PLAIN. PLAIN is the default value. This argument is overridden by the NFNTSTYL= argument.

specifies a URL for the image that you want to use in the background of the diagram. See also the IBACKPOS= argument.

specifies how to display the background image in the IBACKLOC= argument. Specify one of the following options:

specifies the URL that is displayed when you click on the background image. This argument is valid only when the value of the IBACKPOS= argument is POSITION. If you are including the Powered by SAS logo, then you must use this argument to link the image to the SAS Web site.

specifies the x (horizontal) and y (vertical) pixel coordinates of the upper left corner of the background image. Positive values are measured from the upper left corner of the background area. Negative values are measured from the lower right corner of the background area. These values are valid only if the value of the IBACKPOS= argument is POSITION. Always specify both the IBACKX= and IBACKY= arguments.

specifies the appearance of the node border line, using one of the following values:

the default value N indicates that size information from the resource bundle is not to be used for sizing the two dialog boxes that can be invoked from the pop-up menu that appears when a user right-mouse-clicks on a diagram. The two dialog boxes are the About dialog box and the Mouse Help dialog box.

when the value is Y (default), indicates that the link width values are to be scaled into the range of 0–1. Specifying N indicates that the link widths are already scaled into that range. This argument is valid only when the value of the DATATYPE= argument is ASSOC.

specifies whether initially to display all arc lines between nodes. Specifying N suppresses all arc lines. The default value is Y.

specifies the angular spreading factor for the layout of the diagram. The value specified must be greater than or equal to 1.0. The default value is 1.25.

indicates whether pop-up data tips are displayed when the cursor is positioned over nodes or links or both. The default value is Y.

when the value is TRACKING (default), indicates that the pop-up data tips windows are to move with the cursor while the cursor moves within the area of a single node or link.

determines the growth direction of the node and link diagram using the following values.

specifies the angular width of the diagram in degrees. Valid values must be greater than zero and less than 360. The default value is 60. For details, see the TREEDIR= and ANGLE= arguments.

specifies the zoom value that is used for the initial display of the diagram. After the initial display, the Web user can change the zoom percentage dragging the mouse up and down while pressing the Ctrl + left mouse button. Selecting the Refresh button on the browser runs the applet and restores the initial zoom setting. The default value is 100%. The initial diagram can be scaled up with a value greater than 100 or scaled down with a value less than 100.
