is to revert the same scale for all charts, then to select
the requested charts and to activate same scale.
Note: If you apply the same scale operation to charts
that have value axis breaks, the breaks are automatically
removed (see Value axis break on page 42). As long as
breaks are present, it is impossible to make the selected
charts visually comparable.
Logarithmic Scale
You can switch to a logarithmic scale by using the
Set Logarithmic Scale button from the value axis
context menu. To revert to a linear scale choose Set
Linear Scale.
Note: Due to a limitation in Microsoft Graph an axis
with a logarithmic scale can only have tickmarks at powers
of 10, e.g. at 0.1, 1, 10. The axis must also begin
and end at a power of 10.
Logarithmic scaling is not supported when it is mathematically
not appropriate. Negative values are placed
on the baseline and an exclamation mark is shown
next to the label explaining that the value cannot be
represented on a logarithmic scale. Also, an axis always
uses a linear scale if multiple series that are added up
to a total are associated with the axis.
Secondary Axis
Charts containing lines may have an additional, secondary
y-axis. You can add a secondary y-axis, and associate
a line with this axis, by highlighting a line and
selecting the Set to Right/Left Axis button from the
line context menu. If a chart has two y-axes, then you
can use the same Set to Right/Left Axis button to alter
Column chart, line chart and area chart 44
the y-axis association of individual lines in the chart. A
secondary axis is a fully-fledged value axis (Value axis
on page 40) and may be scaled independently.
Gap width and category gap
The basic spacing between columns in a chart is specified
by the gap width. Extra spacing between individual
pairs of columns may be added by inserting a category
gap.
The gap width for all columns can be altered by clicking
on the baseline and dragging the handle a small
distance. The handle snaps to the default gap width.
In order to achieve a consistent appearance for charts
throughout your presentation, the default gap width
should be used when possible.
Category gaps can be introduced by dragging the same
handle further to the right until the category gap tooltip
