将示例代码中的内容保存为json格式的数据,比如将上面的保存为basicLine.json
{
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
}
《使用phantomjs生成highcharts》

二、利用java+phantomjs生成highcharts图片
具体思路:
- 使用highchart-java-api的jar,配置待生成的highcharts的属性和Data;
- 将上一步生成的数据转换为json格式,供phantomjs使用;
- 使用phantomjs和json文件,生成图片;
highchart-java-api可以使用:
<dependency>
<groupId>nl.pvanassen</groupId>
<artifactId>highchart-java-api</artifactId>
<version>0.1.1</version>
</dependency>
