sua collection precisa ter beans com as informações que vc quer exibir…

A sua propriedade ‘grafico’ deve ser declarada no form bean do struts-config ou na sua classe ActionForm
<form-bean name="frmCadUsuario" type="org.apache.struts.validator.DynaActionForm">
<form-property name="grafico" type="java.lang.String"/>
</form-bean>
