Question

我从谷歌开发者网站上阅读了API参考资料。对于物料折线图，来自example的here。谁能告诉我如何删除底部的“月”？我认为它应该由一些代码来完成：

hAxis: {
  title: ''
}

此外，大多数hAxis和vAxis功能都不起作用。

Answer 1

这是正确的，以下选项将删除x轴标题...

hAxis: {
  title: ''
},

请务必使用材料图表的选项转换方法...

                         //convert options
materialChart.draw(data, google.charts.Line.convertOptions(materialOptions));

请参阅以下工作代码段...

＆＃13;

google.charts.load('current', {'packages':['line', 'corechart']});
      google.charts.setOnLoadCallback(drawChart);

    function drawChart() {

      var button = document.getElementById('change-chart');
      var chartDiv = document.getElementById('chart_div');

      var data = new google.visualization.DataTable();
      data.addColumn('date', 'Month');
      data.addColumn('number', "Average Temperature");
      data.addColumn('number', "Average Hours of Daylight");

      data.addRows([
        [new Date(2014, 0),  -.5,  5.7],
        [new Date(2014, 1),   .4,  8.7],
        [new Date(2014, 2),   .5,   12],
        [new Date(2014, 3),  2.9, 15.3],
        [new Date(2014, 4),  6.3, 18.6],
        [new Date(2014, 5),    9, 20.9],
        [new Date(2014, 6), 10.6, 19.8],
        [new Date(2014, 7), 10.3, 16.6],
        [new Date(2014, 8),  7.4, 13.3],
        [new Date(2014, 9),  4.4,  9.9],
        [new Date(2014, 10), 1.1,  6.6],
        [new Date(2014, 11), -.2,  4.5]
      ]);

      var materialOptions = {
        chart: {
          title: 'Average Temperatures and Daylight in Iceland Throughout the Year'
        },
        width: 900,
        height: 500,
        series: {
          // Gives each series an axis name that matches the Y-axis below.
          0: {axis: 'Temps'},
          1: {axis: 'Daylight'}
        },
        hAxis: {
        	title: ''
        },
        axes: {
          // Adds labels to each axis; they don't have to match the axis names.
          y: {
            Temps: {label: 'Temps (Celsius)'},
            Daylight: {label: 'Daylight'}
          }
        }
      };

      var classicOptions = {
        title: 'Average Temperatures and Daylight in Iceland Throughout the Year',
        width: 900,
        height: 500,
        // Gives each series an axis that matches the vAxes number below.
        series: {
          0: {targetAxisIndex: 0},
          1: {targetAxisIndex: 1}
        },
        vAxes: {
          // Adds titles to each axis.
          0: {title: 'Temps (Celsius)'},
          1: {title: 'Daylight'}
        },
        hAxis: {
          ticks: [new Date(2014, 0), new Date(2014, 1), new Date(2014, 2), new Date(2014, 3),
                  new Date(2014, 4),  new Date(2014, 5), new Date(2014, 6), new Date(2014, 7),
                  new Date(2014, 8), new Date(2014, 9), new Date(2014, 10), new Date(2014, 11)
                 ]
        },
        vAxis: {
          viewWindow: {
            max: 30
          }
        }
      };

      function drawMaterialChart() {
        var materialChart = new google.charts.Line(chartDiv);
        materialChart.draw(data, google.charts.Line.convertOptions(materialOptions));
        button.innerText = 'Change to Classic';
        button.onclick = drawClassicChart;
      }

      function drawClassicChart() {
        var classicChart = new google.visualization.LineChart(chartDiv);
        classicChart.draw(data, classicOptions);
        button.innerText = 'Change to Material';
        button.onclick = drawMaterialChart;
      }

      drawMaterialChart();

    }

＆＃13;

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
     <button id="change-chart">Change to Classic</button>
  <br><br>
  <div id="chart_div"></div>

＆＃13;

注意：转换方法不适用于所有选项，
很多人根本得不到支持......

另一条路线是使用带有以下选项的经典图表......

theme: 'material'
