问题描述
使用 Google Charts 条形图,是否可以更改一个条形的颜色.例如,我想将 2006 年的数据设为红色(其他条形为蓝色).
With Google Charts bar graph, is it possible to to change the color of one bar. For example I'd like to make the 2006 data red (other bars are blue).
function drawVisualization() {
// Create and populate the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Year');
data.addColumn('number', 'Sales');
data.addRows(4);
data.setValue(0, 0, '2004');
data.setValue(0, 1, 1000);
data.setValue(1, 0, '2005');
data.setValue(1, 1, 1170);
/* NEED TO MAKE THIS BAR RED? */
data.setValue(2, 0, '2006');
data.setValue(2, 1, 1400);
data.setValue(3, 0, '2007');
data.setValue(3, 1, 1030);
chart = new google.visualization.BarChart(document.getElementById('visualization'));
chart.draw(data, {width: 400, height: 240, title: 'Company Performance',
vAxis: {title: 'Year', titleTextStyle: {color: 'red'}}
});
}
推荐答案
这是更改颜色的代码示例.请注意,颜色"选项接受字符串数组.
Here is a code sample that changes the color. Note that the"colors" option accepts an array of strings.
var options = {
title: 'Company Performance',
hAxis: {title: 'Year', titleTextStyle: {color: 'red'}},
colors: ['red','green'],
is3D:true
};
