To draw the Box graph:
- 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 |
| | | | | | | |
- Select the range A2..G6. The columns will now be
highlighted.
- Select New Graph from the Graph menu and display its
submenu.
- Select Box Graph from the New Graph submenu. NExS
displays a window containing a Box graph.
- 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.
Figure 13.21: Box Graph
Just as with Line, Bar, and Hi Lo charts, Box graphs can show
multiple sets of data.
