Net charts
A net chart is similar to polar or radar graphs. They are useful for
comparing data that are not time series, but show different
circumstances, such as variables in a scientific experiment or
direction. The poles of the net chart are the y-axes of other charts.
Generally, between three and eight axes are best; any more and this
type of chart becomes confusing.
Stock charts
A stock chart is a specialized column graph specifically for stocks
and shares. You can choose traditional lines, candlestick, and two-
column type charts. The data required for these charts is quite
specialized, with series for opening price, closing price, and high
and low prices. The x-axis represents a time series.
Column and line charts
A column and line chart is a combination of two other chart types. It
is useful for combining two distinct but related data series, for
example sales over time (column) and the profit margin trends (line).
Entering chart data
Opening a chart data window
1) If the chart is not already in edit mode (with a gray border),
double-click it. The main toolbar now shows tools specifically for
charts. (If the main toolbar is not showing, select View >
Toolbars > Main Toolbar.)
2) Click the Chart Data icon or select View > Chart Data
Table, or right-click on the chart and choose Chart Data Table.
The Data Table dialog box (Figure 134) appears.
Tip
If you drag the Data Table dialog box so that your chart is
visible, you can then immediately see the results of each change
after clicking in a different cell.
