I’m not good with it but this will get it done. You might have to work it differently. But if you put how you are creating your chart then I can make it an exact match. Essentially you will want this: 

callbacks: {
    title: function(tooltipItem, data) {
        return this._data.labels[tooltipItem[0].index];
    },

    label: function(tooltipItem, data){
        var lab = data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index];
        return lab === 0 ? "Não Avaliado" : "Avaliação Geral: " + lab;
    }
}
