Using the Array Viewer

The Array Viewer displays array data in two adjustable panes:

• The top pane shows the array's numeric values in a scrollable spreadsheet.
• The bottom pane displays a graphical view of the array data as a three-dimensional surface. Other viewing modes include graphical representation of the array data as an image map, a vector graph, or a plane graph.

The following figure shows the Array Viewer, with a height plot view:

When you initially start Array Viewer from the Compaq Array Viewer program group (or by double-clicking the file Aview.exe), some typical actions include:

• Open a file

  To open a file, in the File menu, click Open. Select the folder and the file you want to open. You can open AGL files (as shown), HDF files, and other file types. The Array Visualizer Sample graphics files are installed during a Complete installation.

• Display and move the marker

  To display the red marker, click the appropriate button on the toolbar.

  To move the marker, do one of the following:

  • Double-click the appropriate area on the graph.
  • Use the arrow (cursor) keys. Pressing an arrow key moves the marker one cell in the direction indicated by the key. Pressing Shift and an arrow key moves the marker by 10% of the array width or height.
  • Double-click the appropriate array element cell in the top pane.

• Adjust the sizes of the top pane (array values) and bottom pane (graph view)

  Move the pointer to the boundary between the two panes and drag the boundary to the desired size. Alternatively, in the View menu, click Split. Adjust the top and bottom pane sizes as needed by dragging the pointer.
