Setting the Node Size

Select Options ® Node Size to call up the Node Size dialog box. This dialog box lets you set the size of hierarchy nodes and the window "cells" in which they are displayed.

Window "cells" are sections of an imaginary grid laid over the hierarchy. Each cell contains one node. The cell size is the amount of space within which a node is displayed. Cell size is set using two options:

  • Zoom factor
  • Relative width

The node size variables determine how much (what percent) of the cell the hierarchy box actually occupies. These variables are:

  • Node width
  • Node height

Setting Values

For each of the options in this dialog box, the number to the left of each option tells you the current value. You can click on the up-arrow to increase the value, or on the down-arrow to decrease it. As you click, you see the current value at left getting bigger or smaller.

You can also click on the number itself, delete the current value, and type in a new one. Each option has a minimum and maximum. If you type in a number outside this range, SAP Hierarchy assumes the highest or lowest possible legal value.

The Node Size menu has two extra buttons in addition to the normal Continue, Text, Cancel and Help buttons:

  • The Default button sets all Node Size options to the default values specified by SAP Hierarchy.
  • The Adapt button sets all Node Size options to values optimal for displaying the entire hierarchy in the window. This is the largest possible cell size at which the whole hierarchy can be displayed.

The following sections explain how to use the four options in the Node Size menu.

How the Size of the Hierarchy Display is Determined

Window "cells" are sections of an imaginary grid laid over the hierarchy. Each cell contains one node. The dimensions of this grid (number of cells across and down) are determined by the hierarchy itself. If the widest hierarchy level is five nodes across, the grid must be five cells wide. If the hierarchy is nine levels deep, the grid is nine cells high.

Thus cell size, together with the dimensions of the hierarchy itself, determines the size (height and breadth) of the total hierarchy display. The node size (as a percentage of cell size) does not affect the total hierarchy size: it merely determines how much of the total display is space.

SAP Hierarchy specifies a default size (height and width) for cells. This default cell size is used to enhance readability and is completely independent of the number of nodes in the hierarchy. However, you can alter the cell size using the Zoom factor and Relative width options.

Setting the Zoom Factor

The zoom factor is the enlargement factor used to determine the size of the hierarchy cells. The Zoom factor value is a percentage of the default size (height and width) of the cell.

Possible percentage values range from 10% to 500%. For example, if you choose a zoom factor of 500, hierarchy cells (and thus the hierarchy as a whole) are five times as large as the default size. As long as you don't change any other variables (Relative width, Node width or Node Height), the nodes in the cells will likewise appear five times larger: you see only one fifth as many (approximately) as the number visible at the default size.

Cell size has a default height/width ratio. You can vary this ratio using the Relative width option.

You can vary how much of the cell the node takes up by setting the Node width and Node height options.

Setting the Relative Width

The Relative width option tells you how much wider the cell is than it is high.

This variable is a percentage: if its value is 200, the cell is twice as wide as it is high. If its value is 100, the cell is square. (This becomes apparent when the Node Width and Node Height values are equal to each other.)

When you set the Relative width option, you are essentially setting the cell width, where the cell height is assumed constant:

  • Cell width = Relative Width x Cell height

You can see your changes to Relative Width in the display (the hierarchy boxes grow appropriately fatter or thinner) as long as you leave the other variables (Zoom factor, Node Width and Node Height) unchanged.

If you want to change the cell height in addition to cell width, you must adjust both the Zoom factor and Relative width options.

Setting the Node Width

This option sets the node width to be a percentage of the calculated cell width.

Node width merely tells how much of the cell width the node takes up. Node width has no effect on how wide the cell itself is. (See "Setting the Zoom Factor" and "Setting the Relative Width".)

Legitimate values for the Node width option range from 10% to 90%.

Setting the Node Height

This option sets the node height to be a percentage of the calculated cell height.

Node height merely tells how much of the cell height the node takes up. Node height has no effect on how high the cell itself is. (See "Setting the Zoom Factor" and "Setting the Relative Width".)

Legitimate values for the Node height option range from 10% to 95%.
