Hi @COSTA
welcome to the community 
Yes that is possible. Lets say you have a parameter called “vl or qtd” with the two options “value” and “quantity”.
Now you create a calculated field:
ifelse({vl or qtd} = "value", {vl_transacoes},
ifelse({vl or qtd} = "quantity", {qtd_transacoes}, NULL)
)
Now you have to show the parameter on your sheet and create a visual with the calculated field.
Best regards,
Nico
