Question

我在Google可视化仪表板中提供了一个有效的示例CategoryFilter。
进行选择时，它将过滤表并仅显示所选值的结果。

是否有一个CategoryFilter 排除所选值？

google.charts.load('current', {
  'packages': ['corechart', 'table', 'gauge', 'controls', 'charteditor']
});

renderChart_onPageLoad();

function renderChart_onPageLoad() {
  google.charts.setOnLoadCallback(function() {
    drawTable();
  }); //END setOnLoadCallback
} //END function renderChart_onEvent

function drawTable() {
  var jsonArray = jsonDataArray_1to1(json);

  //Modify header row to include id and label
  jsonArray = arrayHeaderRow_id_label_date(jsonArray);
  console.log('jsonArray'); console.log(jsonArray);

  var data = google.visualization.arrayToDataTable(jsonArray, false); // 'false' means that the first row contains labels, not data.
  //console.log('data');
  //console.log(data);

  var dashboard = new google.visualization.Dashboard(document.getElementById('div_dashboard'));

  var categoryPicker1 = new google.visualization.ControlWrapper({
    'controlType': 'CategoryFilter',

您可以独立绘制表格和类别过滤器，而无需仪表板，
然后使用类别过滤器上的'statechange'事件在表格上设置过滤器。

var categoryPicker1 = new google.visualization.ControlWrapper({
  'controlType': 'CategoryFilter',
  'containerId': 'div_categoryPicker1',
  dataTable: data,
  'matchType': 'any',
  'options': {
    'filterColumnIndex': 0, //Column used in control
    'ui': {
      'label': 'Is exclude selection possible?',
      //'labelSeparator': ':',
      'labelStacking': 'vertical',
      'selectedValuesLayout': 'belowWrapping',
      'allowTyping': false,
      'allowMultiple': false,
      'allowNone': true
    }
  }
});

google.visualization.events.addListener(categoryPicker1, 'statechange', function () {
  var visibleRows = data.getFilteredRows([{
    column: categoryPicker1.getOption('filterColumnIndex'),
    test: function (value) {
      return (categoryPicker1.getState().selectedValues.indexOf(value) === -1);
    }
  }]);

  table.setView({
    rows: visibleRows
  });
  table.draw();
});

var table = new google.visualization.ChartWrapper({
  chartType: 'Table',
  containerId: 'div_table',
  dataTable: data,
  options: {
    allowHtml: true
  }
});

table.draw();
categoryPicker1.draw();
