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.
