Hi Manuel,
the problem here is that the tool is monitoring the Series underneath the cursor and in that case it detects that the cursor is over one of the Charts.
A solution to this would be to make use of the TabStop property of the component ( Chart in that case ) to select which Chart object you want to be active when the user is moving the cursor over it.
You could try to set to true or false the one you prefer to be active. You can also play with the OnMouseMove event, and set the Chart Enable to true or false.
