gannt图形由google bar chart形成：每个bar的颜色不同 [英] gannt chart formed by google bar chart: different color to each bar

问题描述

我使用Google图表编写了以下类型的甘特图，但我想为每个栏分配不同的颜色。现在在我的情况，因为我给一个透明的颜色分隔符，我不明白我如何可以分配不同的颜色到每个剩余的栏。

I have the following sort of gantt chart coded up using Google Charts, but I would like to assign different color to each bar. Now in my case since I am assigning a transparent color to spacer , I dont understand how I can assign a different color to each remaining bar.

这可能归结为在不同的栏中指定不同颜色的相同系列。

This probably comes down to assigning the same series in different bars different colors.

希望theyd创建一个google甘特图表

Its a nasty way of doing it. Wish theyd make a google gantt chart

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

function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Name');
data.addColumn('timeofday', 'spacer');
data.addColumn('timeofday', 'Runtime');
data.addColumn('timeofday', 'Runtime');
data.addColumn('timeofday', 'Runtime');
data.addColumn('timeofday', 'Runtime');

data.addRow(['PIPE', [3, 0, 0],
    [4, 30, 0],
    [0, 0, 0],
             [0, 0, 0],
    [0, 0, 0]
]);
data.addRow(['CNI', [1, 0, 0],
    [0, 0, 0],
    [7, 30, 0],
             [0, 0, 0],
    [0, 0, 0]
]);
data.addRow(['PEVC', [7, 0, 0],
    [0, 0, 0],
    [0, 0, 0],
    [1, 0, 0],
    [0, 0, 0]
]);

data.addRow(['MA', [7, 0, 0],
    [0, 0, 0],
    [0, 0, 0],
             [0, 0, 0],
    [1, 0, 0]
]);

var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
chart.draw(data, {
    isStacked: true,
    width: 900,
    height: data.getNumberOfRows() * 60,
    title: 'Host Runtimes',
    vAxis: {
        title: 'Content',
        titleTextStyle: {
            color: 'black'
        }
    },
    series: {
        0: {
            visibleInLegend: false,
            color: 'transparent'
        },
        1: {
            visibleInLegend: false,
            color: 'red'
        },
        2: {
            visibleInLegend: false,
            color: 'green'
        },
        3: {
            visibleInLegend: false,
            color: 'blue'
        },
        4: {
            visibleInLegend: false,
            color: 'yellow'
        },
        5: {
            visibleInLegend: false,
            color: 'cyan'
        },
        6: {
            visibleInLegend: false,
            color: 'pink'
        },
        7: {
            visibleInLegend: false,
            color: 'silver'
        }
    }
});
