13.12.1 Drawing the Graph

To draw the Box graph:

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

    A B C D E F G
    1 ylo y yhi varlo median varhi
    2 1 -1 1 3 0 1.5 2
    3 2 0 2 4 1 2.5 3
    4 3 1 3 5 2 3.5 4
    5 4 2 4 6 3 4.5 5
    6 5 3 5 7 4 5.5 6

  2. Select the range A2..G6. The columns will now be highlighted.

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

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

  5. 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 of the box represent the data values in the columns headed by ``yvarlo" and ``yvarhi", respectively. The data in the ``median'' column is displayed using solid squares.

Unlike the Hi Lo graph in the previous section, this Box graph contains only a single data set. But in addition to the Hi Lo graph markers, each data point now has a bounding box and an additional solid marker which represent the variances and median values stored in columns E, G, and F, respectively.

Just as with Line, Bar, and Hi Lo charts, Box graphs can show multiple sets of data.
