Answer 1

check that the chart is not being drawn while hidden

see the following snippet, the chart is hidden by default,
then shown once the chart's 'ready' event fires

notice, it produces the same result as posted in the question...

google.charts.load('current', {
  callback: function () {
    var dataTable = new google.visualization.DataTable();

    dataTable.addColumn("date", "Data");
    dataTable.addColumn("number", "Ton./Hora");
    dataTable.addColumn("number", "Ton./Hora Equiv.");
    dataTable.addColumn("number", "Peso (Ton.)");

    for (var i = 0; i < 12; i++) {
      var temp = new Date();

      dataTable.addRow([new Date(temp.getFullYear(), i)
                        ,(i + 2) * 6
                        ,(i + 1) * 12
                        ,(i + 0) * 18]);
    }

    var date_formatter = new google.visualization.DateFormat({
      pattern: "MMM/yyyy"
    });

    date_formatter.format(dataTable, 0);

    var options = {
      hAxis: {title: 'Período (mês/ano)'},
      series: {0: {type: 'line', targetAxisIndex:0},
               1: {type: 'line', targetAxisIndex:0},
               2: { type: 'bars', targetAxisIndex: 1 }
              },
      legend: { position: "top", textStyle: { fontSize: 14 } },
      width: 1200,
      height: 500
    };

    var container = document.getElementById("div-Equipamento-Produtividade");
    var chart = new google.visualization.ComboChart(container);
    google.visualization.events.addListener(chart, 'ready', function () {
      container.style.display = null;
    });
    chart.draw(dataTable, options);
  },
  packages: ['corechart']
});

<div id="div-Equipamento-Produtividade" style="display: none;"></div>

however, if the container is shown before drawing the chart,
the legend turns out nicely...

google.charts.load('current', {
  callback: function () {
    var dataTable = new google.visualization.DataTable();

    dataTable.addColumn("date", "Data");
    dataTable.addColumn("number", "Ton./Hora");
    dataTable.addColumn("number", "Ton./Hora Equiv.");
    dataTable.addColumn("number", "Peso (Ton.)");

    for (var i = 0; i < 12; i++) {
      var temp = new Date();

      dataTable.addRow([new Date(temp.getFullYear(), i)
                        ,(i + 2) * 6
                        ,(i + 1) * 12
                        ,(i + 0) * 18]);
    }

    var date_formatter = new google.visualization.DateFormat({
      pattern: "MMM/yyyy"
    });

    date_formatter.format(dataTable, 0);

    var options = {
      hAxis: {title: 'Período (mês/ano)'},
      series: {0: {type: 'line', targetAxisIndex:0},
               1: {type: 'line', targetAxisIndex:0},
               2: { type: 'bars', targetAxisIndex: 1 }
              },
      legend: { position: "top", textStyle: { fontSize: 14 } },
      width: 1200,
      height: 500
    };

    var container = document.getElementById("div-Equipamento-Produtividade");
    container.style.display = null;
    var chart = new google.visualization.ComboChart(container);
    chart.draw(dataTable, options);
  },
  packages: ['corechart']
});

<div id="div-Equipamento-Produtividade" style="display: none;"></div>

Answer 2

Every framework or code that hides the chart DIV using "display: none" will make legends to overlap when the chart is draw inside an inactive DIV.

Hidding the chart DIV with "visibility: hidden" works fine, with no overlapping.

I had this issue and only solved it coding the NAV features by myself, without using Bootstrap/JQuery/etc...
