javascript - 谷歌图表 : How to use dashboard with new Material charts?

Question

好像dashboard仅使用旧方法以“经典图表”使用的方式加载其库。我怎样才能让仪表板与新的“ Material ”谷歌图表一起工作？特别是 line graph

Material 图表jsfiddle:https://jsfiddle.net/yzhsf1gv/3/

仪表板 jsiddle:https://jsfiddle.net/job30vwy/

我本能的猜测是

  google.charts.load('current', {'packages': ['line', 'controls']});

但这似乎不起作用

Answer 1

似乎在这里工作...？

只需在 ChartWrapper chartType 中指定 Material 图表...

'chartType': 'Line',

对比

'chartType': 'LineChart',

使用与您在此处指定的相同的类名 -->

new google.charts.-->Line(document.getElementById('chart_div'))

来自 fiddle fork

google.charts.load('current', {'packages':['line', 'controls']});
      google.charts.setOnLoadCallback(drawStuff);

      function drawStuff() {

        var dashboard = new google.visualization.Dashboard(
          document.getElementById('programmatic_dashboard_div'));

        // We omit "var" so that programmaticSlider is visible to changeRange.
        programmaticSlider = new google.visualization.ControlWrapper({
          'controlType': 'NumberRangeFilter',
          'containerId': 'programmatic_control_div',
          'options': {
            'filterColumnLabel': 'Donuts eaten',
            'ui': {'labelStacking': 'vertical'}
          }
        });

       programmaticChart  = new google.visualization.ChartWrapper({
        'chartType': 'Line',
        'containerId': 'programmatic_chart_div',
        'options': {
          'width': 300,
          'height': 300,
          'legend': 'none',
          'chartArea': {'left': 15, 'top': 15, 'right': 0, 'bottom': 0},
          'pieSliceText': 'value'
        }
      });
  
      var data = google.visualization.arrayToDataTable([
        ['Name', 'Donuts eaten'],
        ['Michael' , 5],
        ['Elisa', 7],
        ['Robert', 3],
        ['John', 2],
        ['Jessica', 6],
        ['Aaron', 1],
        ['Margareth', 8]
      ]);

      dashboard.bind(programmaticSlider, programmaticChart);
      dashboard.draw(data);
    }
