Google的时间轴图表栏中的颜色基于特定值

Question

我想为酒吧创建颜色组。以下示例是raw。我想添加一个类别类型的列，并根据该类别我将为该栏添加颜色。

类似的东西：

列

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

订单

[ '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，条形图应具有特定颜色。

Answer 1

时间轴可视化中没有任何内容可以为您执行此操作，但您可以将colors选项设置为使条形图正确颜色所需的任何选项。您可以解析DataTable以构建colors数组，然后使用DataView从时间轴隐藏您的类别列（因为时间轴不知道如何处理它）。这是一个例子：

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});

使用未记录的＆＃39;样式＆＃39;在我的工作示例中看到的角色： 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});

Answer 3

您必须使用选项：

    timeline: {
        colorByRowLabel: true
    }

来自google docs： timeline.colorByRowLabel 默认值布尔值false
如果设置为true，则对行上的每个条形颜色相同。默认情况下，每个条形标签使用一种颜色。

Answer 4

我确实喜欢这个，对我来说很好用。

var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'Name' });
dataTable.addColumn({ type: 'string', id: 'JobType' });
dataTable.addColumn({ type: 'string', role: 'style' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });

for (var j = 0; j < model.JobType.length; j++)
{
    var jbt = model.JobType;
    var ColorValue = null;

    if (jbt == "Job A"){
        ColorValue = "#AF0BEA";
    }
    else if (jbt == "Job B")
    {
        ColorValue = "#19c362";
    }
    else if (jbt == "Job C")
    {
        ColorValue = "#091F8B";
    }
    else if (jbt == "Job D")
    {
        ColorValue = "#592df7";
    }
    else if (jbt == "Job E")
    {
        ColorValue = "#d3401b";
    }

    dataTable.addRows([[name, jbt, ColorValue, startdate, endDate]]);
}

Answer 5

//set fixed colors
var colors = [];
var colorMap = {
  'Maschine in Produktion':                       '#7baaf7',
  'Behälterwechsel':                              '#e67c73',
  'Auftragsgemäßes Rüsten von W.Z. und Material': '#f7cb4d',
  'Unterbrechung':                                '#57ba8a',
  'neues Werkzeug einfahren':                     '#c47ed0',
  'Produktqualität(vermessen der Teile)':         '#4dc5d4',
  'frei':                                         '#ff9b7b',
  'Werkzeugschaden':                              '#bbba66',
  'Coilmaterial (nicht geeignet)':                '#8d97d3',
  'neues Werkzeug einfahren':                     '#f5cfff'
}

for (var i = 0; i < data.getNumberOfRows(); i++) {      
  colors.push(colorMap[data.getValue(i, 0)]);
}

var unique = colors.filter(function(itm, i, a) {
  return i == colors.indexOf(itm);
});


var options = {
  height:   800, 
  hAxis:        {format: isDay == 1 ? 'HH:MM:SS' : 'dd.MM.yyyy HH:MM:SS'},
  tooltip:  {isHtml: true},
  legend:   'none',
  avoidOverlappingGridLines: false,
  colors:   unique
};

chart.draw(data, options);

这对我来说非常有效。旧代码的主要问题是，colors数组只是一个数组，而不是唯一的Hashmap。您可以只使用自定义滤镜功能以获得独特的颜色。

Answer 6

我已经尝试过类似的方法，并且可以正常工作，并且能够为网格中的不同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'};

Answer 7

您必须将角色样式放在数组的中间。它必须必须在中间才能正常工作。我尝试将其推入数组的末尾，但没有用。

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', role: 'style' });      <===========
    dataTable.addColumn({ type: 'date', id: 'Start' });
    dataTable.addColumn({ type: 'date', id: 'End' });
}
