我想为这些条形画一组颜色。下面的例子是原始的。我想添加一个类别类型的列，基于该类别，我将对条形图进行着色。

类似于：

列

dataTable.addColumn({ type: 'string', id: 'Category' });

线

[ 'GROUP #1', 'CategoryA', 'C00001', new Date(2014, 0, 1), new Date(2014, 0, 31) ],
[ 'GROUP #1', 'CategoryA', 'C00002', new Date(2014, 1, 1), new Date(2014, 1, 28) ],
[ 'GROUP #1', 'CategoryA', 'C00003', new Date(2014, 3, 1),  new Date(2014, 3, 15) ],
[ 'GROUP #1', 'CategoryB', 'C00003', new Date(2014, 0, 21),  new Date(2014, 2, 19) ],
[ 'GROUP #1', 'CategoryA', 'C00004', new Date(2014, 0, 1),  new Date(2014, 0, 15) ],
[ 'GROUP #2', 'CategoryC', 'C00005', new Date(2014, 2, 8),  new Date(2014, 2, 15) ],
[ 'GROUP #3', 'CategoryC', 'C00006', new Date(2014, 5, 1),  new Date(2014, 5, 15) ],
[ 'GROUP #4', 'CategoryA', 'C00007', new Date(2014, 1, 15),  new Date(2014, 1, 25) ]]);

根据类别，条形图应该有特定的颜色。

google.load("visualization", "1", {packages: ["timeline"]});
google.setOnLoadCallback(drawChart);

function drawChart() {
    var container = document.getElementById('example4.2');
    var chart = new google.visualization.Timeline(container);
    var dataTable = new google.visualization.DataTable();

    dataTable.addColumn({ type: 'string', id: 'Group' });
    dataTable.addColumn({ type: 'string', id: 'ID' });
    dataTable.addColumn({ type: 'date', id: 'Start' });
    dataTable.addColumn({ type: 'date', id: 'End' });
    dataTable.addRows([
        [ 'GROUP #1', 'C00001', new Date(2014, 0, 1), new Date(2014, 0, 31) ],
        [ 'GROUP #1', 'C00002', new Date(2014, 1, 1), new Date(2014, 1, 28) ],
        [ 'GROUP #1', 'C00003', new Date(2014, 3, 1),  new Date(2014, 3, 15) ],
        [ 'GROUP #1', 'C00003', new Date(2014, 0, 21),  new Date(2014, 2, 19) ],
        [ 'GROUP #1', 'C00004', new Date(2014, 0, 1),  new Date(2014, 0, 15) ],
        [ 'GROUP #2', 'C00005', new Date(2014, 2, 8),  new Date(2014, 2, 15) ],
        [ 'GROUP #3', 'C00006', new Date(2014, 5, 1),  new Date(2014, 5, 15) ],
        [ 'GROUP #4', 'C00007', new Date(2014, 1, 15),  new Date(2014, 1, 25) ]]);

    var rowHeight = 41;
    var chartHeight = (dataTable.getNumberOfRows() + 1) * rowHeight;

    var options = {
        timeline: { 
            groupByRowLabel: true,
            rowLabelStyle: {
                fontName: 'Roboto Condensed',
                fontSize: 14,
                color: '#333333'
            },
            barLabelStyle: {
                fontName: 'Roboto Condensed',
                fontSize: 14
            }
        },                          
        avoidOverlappingGridLines: true,
        height: chartHeight,
        width: '100%'
    };

    chart.draw(dataTable, options);
}

时间线可视化中没有任何东西可以为您做这件事，但是您可以将colors选项设置为您需要的任何东西，以获得正确的颜色。您可以解析DataTable来构建颜色数组，然后使用DataView来向Timeline隐藏类别列(因为Timeline不知道如何处理它)。下面是一个例子：

function drawChart() {
    var container = document.getElementById('example4.2');
    var chart = new google.visualization.Timeline(container);
    var dataTable = new google.visualization.DataTable();

    dataTable.addColumn({ type: 'string', id: 'Group' });
    dataTable.addColumn({ type: 'string', id: 'Category' });
    dataTable.addColumn({ type: 'string', id: 'ID' });
    dataTable.addColumn({ type: 'date', id: 'Start' });
    dataTable.addColumn({ type: 'date', id: 'End' });
    dataTable.addRows([
        [ 'GROUP #1', 'CategoryA', 'C00001', new Date(2014, 0, 1), new Date(2014, 0, 31) ],
        [ 'GROUP #1', 'CategoryA', 'C00002', new Date(2014, 1, 1), new Date(2014, 1, 28) ],
        [ 'GROUP #1', 'CategoryA', 'C00003', new Date(2014, 3, 1),  new Date(2014, 3, 15) ],
        [ 'GROUP #1', 'CategoryB', 'C00003', new Date(2014, 0, 21),  new Date(2014, 2, 19) ],
        [ 'GROUP #1', 'CategoryA', 'C00004', new Date(2014, 0, 1),  new Date(2014, 0, 15) ],
        [ 'GROUP #2', 'CategoryC', 'C00005', new Date(2014, 2, 8),  new Date(2014, 2, 15) ],
        [ 'GROUP #3', 'CategoryC', 'C00006', new Date(2014, 5, 1),  new Date(2014, 5, 15) ],
        [ 'GROUP #4', 'CategoryA', 'C00007', new Date(2014, 1, 15),  new Date(2014, 1, 25) ]
    ]);

    var colors = [];
    var colorMap = {
        // should contain a map of category -> color for every category
        CategoryA: '#e63b6f',
        CategoryB: '#19c362',
        CategoryC: '#592df7'
    }
    for (var i = 0; i < dataTable.getNumberOfRows(); i++) {
        colors.push(colorMap[dataTable.getValue(i, 1)]);
    }

    var rowHeight = 41;
    var chartHeight = (dataTable.getNumberOfRows() + 1) * rowHeight;

    var options = {
        timeline: { 
            groupByRowLabel: true,
            rowLabelStyle: {
                fontName: 'Roboto Condensed',
                fontSize: 14,
                color: '#333333'
            },
            barLabelStyle: {
                fontName: 'Roboto Condensed',
                fontSize: 14
            }
        },                          
        avoidOverlappingGridLines: true,
        height: chartHeight,
        width: '100%',
        colors: colors
    };

    // use a DataView to hide the category column from the Timeline
    var view = new google.visualization.DataView(dataTable);
    view.setColumns([0, 2, 3, 4]);

    chart.draw(view, options);
}
google.load('visualization', '1', {packages:['timeline'], callback: drawChart});

使用我的工作示例中所显示的无文档化的“样式”角色：http://jsfiddle.net/af8jq9aa/1/

function drawChart() {
  var container = document.getElementById('example5.4');
  var chart = new google.visualization.Timeline(container);
  var dataTable = new google.visualization.DataTable();
  dataTable.addColumn({ type: 'string', id: 'Role' });
  dataTable.addColumn({ type: 'string', id: 'Name' });
  dataTable.addColumn({ type: 'string', role: 'style' });
  dataTable.addColumn({ type: 'date', id: 'Start' });
  dataTable.addColumn({ type: 'date', id: 'End' });
  dataTable.addRows([
    [ 'red/green/blue', 'NAME OF BAR (should be RED) (ff0000)', '#ff0000', new Date(1789, 3, 29), new Date(1797, 2, 3) ],
    [ 'red/green/blue', 'NAME OF BAR (should be GREEN) (00ff00)','#00ff00', new Date(1796, 2, 3),  new Date(1801, 2, 3) ],
    [ 'red/green/blue', 'NAME OF BAR (should be BLUE) (0000ff)','#0000ff',  new Date(1801, 2, 3),  new Date(1809, 2, 3) ]]);

  var options = {
  };

  chart.draw(dataTable, options);
}
google.load('visualization', '1', {packages:['timeline'], callback: drawChart});

我尝试过这样的方法，它起了作用，并且能够在网格中为不同的行标签设置不同的颜色。

var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Name' });
dataTable.addColumn({ type: 'string', id: 'ShiftDetails' });
dataTable.addColumn({ type: 'string', role: 'style' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addColumn({ type: 'string', role: 'RowDetails' });
dataTable.addRows([['APHANEE WORARUCHEE','','',new Date(0,0,0,0,0,0),new 
Date(0,0,0,18,0,0),'asdf'],
['CHEW SEOW LEE','','',new Date(0,0,0,0,0,0),new Date(0,0,0,9,0,0),'qwerty'],['TOTAL 
MANPOWER PER HOUR','5','color: red',new Date(0,0,0,0,0,0),new 
Date(0,0,0,1,0,0),'TOTAL'], 
['TOTAL MANPOWER PER HOUR','4','color: red',new Date(0,0,0,1,0,0),new 
Date(0,0,0,2,0,0),'TOTAL']]);

var options = {
timeline: { singleColor: '#8d8', barLabelStyle: { fontName: 'Arial Black', fontSize: 
12 } },backgroundColor: '#ffd'};
