Google Legends Chart - Text Overlap

Question

I use the Google chart on my page, but the legend text is Overlapped, as shown below:

This is my code:

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 < dados.length; i++) {
  var temp = new Date(dados[i].DT_FIM);

  dataTable.addRow([new Date(temp.getFullYear(), temp.getMonth())
                    ,dados[i].TON_HORA
                    ,dados[i].TON_HORA_EQUIV
                    ,dados[i].PES_LIQUI_UNMET]);
}

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 chart = new google.visualization.ComboChart(document.getElementById("div-Equipamento-Produtividade"));
chart.draw(dataTable, options);

Run codeHide result

My charts are on the bootstrap nav tab:

<div id="div-Graficos" class="panel-collapse in">
  <div class="panel-body">
    <ul id="tab-Graficos" class="nav nav nav-tabs nav-justified" role="tablist">
      <li role="presentation" class="active"><a href="#div-Grafico-OEE" aria-controls="div-Grafico-OEE" role="tab" data-toggle="tab">Equipamento - OEE</a></li>
      <li role="presentation"><a href="#div-Grafico-T2" aria-controls="div-Grafico-T2" role="tab" data-toggle="tab">Equipamento - T2</a></li>
      <li role="presentation"><a href="#div-Grafico-Produtividade" aria-controls="div-Grafico-Produtividade" role="tab" data-toggle="tab">Equipamento - Produtividade</a></li>
    </ul>
    <div class="tab-content">
      <div role="tabpanel" class="tab-pane fade in active" id="div-Grafico-OEE">
        <div id="div-Equipamento-OEE" style="width: 900px; height: 500px"></div>
      </div>
      <div role="tabpanel" class="tab-pane fade" id="div-Grafico-T2">
        <div id="div-Equipamento-T2" style="width: 900px; height: 500px"></div>
      </div>
      <div role="tabpanel" class="tab-pane fade" id="div-Grafico-Produtividade">
        <div id="div-Equipamento-Produtividade" style="width: 1200px; height: 500px"></div>
      </div>
    </div>
  </div>
</div>

Run codeHide result

I tried to change the position to "lower", but the problem continued

What am I doing wrong?

Answer 1

check if the chart is drawn while it is hidden

see the following snippet, the chart is hidden by default,
then it is displayed as soon as the chart event is 'ready'triggered

it produces the same result as 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']
});
