The Values property contains all the bubbles in the bubble chart. Each bubble (TRSBubbleChartValue) may have its own Color and Caption. The size of the bubble is specified by the Size property. The size of the bubbles can represent the area of the bubbles or the diameter of the bubble (controlled by the    SizeOption property of TRSBubbleChartValues), which affects the relative size of one bubble to another.
 
Bubble sizes can be negative values, although negative bubbles do not display in the chart by default (    NegativeSizeVisible must be true). When negative bubble sizes are displayed, they use their absolute size and are always drawn using the    NegativeSizeColor.
 

Use the Values collection to add, delete, and modify bubbles in the chart.
