安装
The preferred way to install this extension is through composer.
项目根目录下执行：
php composer.phar require --prefer-dist miloschuman/yii2-highcharts-widget "*"
或者在composer.json中添加
"miloschuman/yii2-highcharts-widget": "*"
后执行composer update.
使用
在view视图中使用该widget：
use miloschuman\highcharts\Highcharts;
描绘饼状图（此处有两种写法，options中的参数可以为数组形式也可以为json格式，格式大致与highcharts中的例子：http://www.hcharts.cn/test/index.php?from=demo&p=39 格式对应）：
echo Highcharts::widget(['options'=>'{"chart": {"plotBackgroundColor": null,"plotBorderWidth": null,"plotShadow": false},"title": {"text": "Browser market shares at a specific website, 2010"},"tooltip": {"pointFormat": "{series.name}: <b>{point.percentage:.1f}%</b>"},"plotOptions": {"pie": {"allowPointSelect": true,"cursor": "pointer","dataLabels": {"enabled": true,"color": "#000000","connectorColor": "#000000","format": "<b>{point.name}</b>: {point.percentage:.1f} %"}}},"series": [{"type": "pie","name": "Browser share","data": [["Firefox", 45.0],["IE", 26.8],{"name": "Chrome","y": 12.8,"sliced": true,"selected": true},["Safari", 8.5],["Opera", 6.2],["Others", 0.7]]}]}']);
