Added events to a special simulation

FIX:
 - The zero value of the charts were been override when the charts were been resizing
 - Check if the zero position has been defined, if it has not been defined, the zero line is not painted
 - The time to check if a event was or not in the observation window was using the default parameter instead the graph value
 - The command to change the graph of a graph support to define values for observer and prediction windows
