13.13.1 Drawing the Westinghouse Graph

To draw the Westinghouse graph:

  1. Enter the following data into the new NExS spreadsheet:

    mean variance
    1 5 0.2
    2 4 0.4
    3 2 0.3
    4 1 0.7
    5 7 0.1
    6 9 0.5

  2. Select the range A2..C7. The columns will now be highlighted.

  3. Select New Graph from the Graph menu and display its submenu.

  4. Select Westinghouse Graph from the New Graph submenu. NExS displays a window containing a Box graph.

  5. Select Y Axis from the Options menu and set the axis label to ``Mean.''

  6. Select Aux. Y Axis from the Options menu and set the axis label to ``Variance.''

  7. Use the Data Sets... dialog box to change the marker for data set 1 to a square. The Box graph will now appear as shown in Figure 13.21. The top and bottom sub-graphs represent the data values in the columns headed by ``mean" and ``variance", respectively.
