By default, the axes
of your visualizations adjust automatically to your data. If you change
the data that is displayed by applying filters or ranks or by drilling
down, then the data ranges and scaling of your axes will change to
fit the data.
For comparison purposes,
you might want to lock the axes and retain the same data ranges and
scaling. To lock an axis, click the
icon beside the axis heading.
To re-enable automatic
adjustments for an axis, click the
icon beside the axis heading.
