You need to create a variable, e.g. vShow in variable overview.
Then create a button with action 'External' - 'Set Variable'
Put the variable name into the appropriate field
and enter as expression
For all chart objects like list boxes you want to hide, enter as conditional show expression in layout tab

You might also consider using a multi box instead of list boxes to save some screen space.
