Enable the Allow Minimize option on the Caption tab. Then minimize the chart to show it like a sort of icon. Or create an icon image of your liking and use that as background image of a text box item. Create a variable vShow and give it the value -1. Add a Set Variable action to the text box using vShow as variable and =NOT vShow as value. Then on the Layout tab of the table enable the option Show Conditional and use as expression =vShow.
