By default, the explorer
applies changes to your visualizations automatically when you change
data roles, filters, or ranks.
To disable automatic
updates, deselect the Auto-update check box
at the bottom of the right pane. When you are ready to apply your
updates, click Update at the bottom of the
right pane.
Note: You can change the default
behavior for new visualizations by deselecting Update
automatically in the Preferences window.
