Using the Selection View

You can use the Selection view to select the parts of the input data you want displayed in a 3D or 2D graph. When you have the display you want, you can switch to the 3D view or 2D view for an enlarged picture. The following figure contains the Selection view (with 2D graph type Stacked Areas and 3D graph type Walls).

The Selection view contains the following parts:

  • A 3D graph of the input data (upper left of the window)
  • A 2D graph of the input data (lower right of the window)

You can set up the 2D graph to display part or all of the values shown in the 3D graph. The 2D graph can never show values not simultaneously displayed in the 3D graph.

  • Selection bars (the horizontal bars below the 3D image)

The selection bars allow you to select which parts of the 3D graph image to represent in the 2D image. You can read row names, column names or page names into the selection bars at any time.

  • Pushbuttons

The pushbuttons provide a selection of important menu options. To use a pushbutton, click on it.

If the input data is a simple list of values (a table with only rows), the Selection view cannot be generated.

Using the Selection Bars

The selection bars are the horizontal bars below the 3D graph. Use the selection bars to choose which parts of the input data you want displayed in the 2D and 3D graphs.

The topmost selection bar contains the title of a graph dimension: the rows or columns. The lower bars list individual rows or columns. The selection bars always contain either the rows or columns, unless you turn on the Stack on/off button. This button fills the selection bars with the names of individual pages (if your input data extends over several pages).

At any given time, one of the selection bars is highlighted.

  • If the top selection bar is highlighted, the 2D graph contains all the values contained in the 3D graph. In this case, values in the 2D graph are displayed in a side-by-side format.
  • If a lower selection bar is highlighted, the 2D graph represents only a slice of the 3D graph. This slice is the row or column named by the highlighted bar.

The highlighted selection bar is also reflected in the base of the 3D graph frame: If the top selection bar is highlighted, the whole border is lit up on the corresponding side of the frame base. If a lower selection bar is highlighted, only the square representing that row or column is lit up.

Each time you highlight a new row or column, a new 2D graph is generated for those values. If the input data contains multiple pages, and you read the pages into the selection bars (using the Stack on/off button), the 3D graph is also regenerated. This action aligns the page names along the row or column axis. Values for the labels (rows or columns) previously aligned along that axis are now stacked vertically.

How to highlight a selection bar

Each time you highlight a new selection bar, you change the contents of the 2D graph. There are 4 ways to highlight a selection bar:

  • Click directly on the selection bar with the mouse.
  • Click on one of the squares in the 3D frame border. This has differing effects, depending on whether the top or a lower selection bar is already lit up.

If the top bar is already lit up, it remains lit up. The contents of the selection bars may change, depending on which side of the graph you click on, but the topmost bar remains highlighted.

If a lower bar is already lit up, clicking can only highlight another lower bar. In this case, it matters where in the frame border you click: the bar corresponding to the square you click on gets lit up. If the clicked square belongs to the side of the graph not currently in the selection bars, that side will be read in and the correct bar lit up.

You cannot always click on individual squares to highlight a selection bar. Some graph types (Walls, Wedges, Surface) may not depict as many segments in the frame border as there are rows or columns for a given side. When this is true, clicking on a segment has no meaning, since the segments do not correspond to particular rows or columns.

  • Press the directional keys (up-arrow and down-arrow).
  • Press F18 or F19 to cycle through the bars. You can also click with the mouse on the corresponding pushbuttons in the graphics window.

Note that you cannot highlight the topmost selection bar (the dimension title) if the selection bars currently contain the names of pages.

How to change the contents of the selection bars

There are 3 ways to read a dimension (the rows, columns or pages) into the selection bars:

  • To read in the rows, click with the mouse anywhere on the left side border of the 3D frame. To read in the columns, click anywhere on the right side.
  • To toggle between rows and columns, you can press either right or left arrow-keys repeatedly.
  • To read the names of pages into the selection bars, click with the mouse on the Stack on/off button. The input data must of course extend over several pages to use this function

Using the Selection View Pushbuttons

The Selection view contains the following pushbuttons:

  • 2D view

Go to the 2D view.

  • 3D view

Go to the 3D view.

  • Groups

Go to Groups view.

  • Stack on/off

The Stack on/off button reads the names of pages into the selection bars. This button is a toggle: click once to read page-names in; click again to replace page-names with the previous contents.

When this button is turned on, both the 3D and 2D graphs are regenerated. In the 3D graph, names of pages replace either row-names or column-names along the left or right axis of the graph. The 3D graph floor now displays either rows-by-pages or pages-by-columns. Values for the dimension replaced (rows or columns) are stacked vertically.

A new 2D graph is also generated for the currently active page. The currently active page is the page highlighted in the selection bars when you turn the Stack on/off button on.

The Stack on/off button always gives you a stacked 3D graph. If you want to reassign rows, columns, and pages to various axes in the graph, but don't necessarily want a stacked graph, use the Dimension Order option (3D Options menu).

This button does not appear in the graphics window if the input data does not include multiple pages.

  • Left

Reads into the selection bars the dimension currently laid out along the rows axis (the left side border of the 3D graph floor).

  • Sel. up

Highlight the next selection bar in the series.

  • Sel. down

Highlight the previous selection bar in the series.

  • Right

Reads into the selection bars the dimension currently laid out along the columns axis (the right side border of the 3D graph floor).

  • First selection

Switch between the current selection bar and the top-most selection bar. If the top-most selection bar is the current selection bar, then First selection automatically switches between the top-most (first) selection bar and the next (second) selection bar.

This button is a toggle: the first click makes a switch, and the next click switches back.

  • Page up

Scroll forward through the different pages of the data. This button does not appear if the input data does not contain multiple pages.

  • Page down

Scroll backward through the different pages of the data. This button does not appear if the input data does not contain multiple pages.
