To get the next number in the sequence, you add 2 to the previous number.
Logarithmic scales
Logarithmic scales are based on multiplication rather than addition. In a logarithmic scale,
the steps increase or decrease in size. Logarithmic scales are based on multiplication (or
division). Consider, for example, the logarithmic sequence:
2, 4, 8, 16, 32
To get the next number in the sequence, you multiply the previous number by 2. We can
say that this sequence represents ``base 2.''
Consider the following sequence:
1, 10, 100, 1000, 10000
This sequence represents ``base 10,'' because you get the next term in the sequence by
multiplying the previous term by 10.
Displaying a logarithmic scale
To display a logarithmic scale:
1. Right-click the chart and select Edit Format.
2. Open the Appearance > Y Axis > Scale property group in the Properties tab.
3. Select Logarithmic.
The Edit Report button is pressed in when you are working in Report View.
4. Select the chart.
5. Click the Properties tab, and then click the Chart Format sub-tab.
Or
Right-click the chart, then select Edit Format from the shortcut menu.
Note: A logarithmic scale uniformly presents percent changes rather than point changes.
In other words, the distance from 1 to 2 (100% increase) is the same as the distance from
2 to 4 (another 100% increase).
Choosing chart data display options
You can modify the chart display in order to:
• show/hide the values – for the data on each chart bar, line, or marker
• select a specific color – for the primary data series (that is, for the bars, lines, or
markers that display the first measure on the chart body)
• show/hide data markers – on Line charts, Bar and Line charts, and Radar charts
• show/hide charts – when there is no data for the dimension(s) or measure(s) on the
axes
