我曾尝试 highcharter 画多元时间序列图

class(EuStockMarkets)
[1] "mts"    "ts"     "matrix"

我注意到 plot 方法里，包含对 ts 对象的支持，所以 plot(EuStockMarkets)

我也注意到 hchart 应该是支持 mts 和 ts 数据类型的画图

methods(hchart)
 [1] hchart.acf*        hchart.character*  hchart.data.frame*
 [4] hchart.default*    hchart.density*    hchart.dist*

[22] hchart.ts*         hchart.xts*       
see '?methods' for accessing help and source code

但是，当我尝试这样画图的时候，就报错了，不知是不是我调用出错了，还是这个包本身不支持
