Question

我结合了我在互联网上找到的两个例子，不幸的是，我必须做错事，因为只有一部分是在Jsfiddle中绘制的

通过这两个例子，我想学习如何创建DateSlider。有人可以指出我的错误吗？第一个例子来自https://blog.smalldo.gs/2013/04/google-chart-tools-walkthrough-part-3/#add-to-dashboard 第二个例子来自interactive charts

google.setOnLoadCallback(drawChart);
function drawChart() {
    var dashboard = new google.visualization.Dashboard(document.getElementById('programmatic_dashboard_div'));


    var data = new google.visualization.DataTable();
        data.addColumn('number', 'Drie');
        data.addColumn('string', 'Name');
        data.addColumn('date', 'Date');
        data.addColumn('number', 'Donuts eaten'); 
        data.addColumn('number', 'Hours Worked');


    data.addRows([
        [33333333,'Michael', new Date(2012,0,2),1,9],
        [33333,'Elisa', new Date(2012,0,3),7,8],
        [3,'Robert', new Date(2012,0,4),9,10],
        [3,'John', new Date(2012,0,5),7,8],
        [3,'Jessica', new Date(2012,0,6),3,5],
        [3,'Aaron', new Date(2012,0,6),7,4],
        [3,'Margareth', new Date(2012,0,7),7,3]
    ]);

    // 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': 'PieChart',
        'containerId': 'programmatic_chart_div',
        'options': {
            'width': 300,
            'height': 300,
            'legend': 'none',
            'chartArea': {'left': 15, 'top': 15, 'right': 0, 'bottom': 0},
            'pieSliceText': 'value'
        }
    });

    dashboard.bind(programmaticSlider, programmaticChart);

    //Create a DataView from the data_table
    var dataView = new google.visualization.DataView(data);

    //Set the first column of the dataview to format as a string, and return the other columns [1, 2 and 3]
   dataView.setColumns([{calc: function(data, row) { return data.getFormattedValue(row, 0); }, type:'string'}, 1, 2, 3,4]);

    // Create a date range slider
    var myDateSlider = new google.visualization.ControlWrapper({
        'controlType': 'ChartRangeFilter',
        'containerId': 'control_div',
        'options': {
            'filterColumnLabel': 'Date'
        }
  });

  // Table visualization
  var myTable = new google.visualization.ChartWrapper({
      'chartType' : 'Table',
      'containerId' : 'table_div'
  });

  dashboard.bind(myDateSlider, myTable);


  // Line chart visualization
  var myLine = new google.visualization.ChartWrapper({
      'chartType' : 'LineChart',
      'containerId' : 'line_div',
  });      

  dashboard.bind(myDateSlider, myLine ); 

  dashboard.draw(dataView);
  }

Answer 1

使用以下两项更改

更改您的代码

首先，

<!-- Put following jsapi library on top, i.e load it before you execute 'google.setOnLoadCallback' -->

<script type="text/javascript" src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization','version':'1.1','packages':['corechart', 'controls']}]}"></script>

其次，

function changeOptions() {
   programmaticChart.setOption('is3D', true);

   //Added following line in your code, 'setView'
   programmaticChart.setView({'columns': [0, 4]});

   programmaticChart.draw();
}

对于日期阅读器，请按照此documentation

进行操作

具有多个控件的dataview
