使用Echarts进行可视化的数据线呈现

由于游戏后台需要统计游戏玩家的支付情况,恰好那天看见同学群里聊天说到了Echarts,于是我就看了眼,一看,哟,还是百度的产品,看了文档,示例,确实很屌的样子啊,于是自己就开始试了,个人还是觉得这个效果挺棒的,清晰地看清了各个渠道、每一天的统计情况,图表是可以放大缩小的,柱状图也能转为折线图,其实我只是用到了Echarts的冰山一角,这是个十分强大的图标工具,官网:http://echarts.baidu.com/ 各位去官网看看文档,看看示例,看看api,就知道这款工具有多么强大,他还支持h5,也就是说,用h5做手机app的时候,也可以在手机端呈现如此强大的报表功能
最终效果如下:

,我就分享一下我做的这个报表的源代码:

然而看完官网你们就知道了,Echarts还能做更多更多的事,我所用到的不是过是其中一小部分而已,这是一个十分强大的报表插件。

大爷赏点儿呗.
