On the problem of mean connecting lines in box plots

[DimeSnow]

What problem does this feature solve?

I need to draw the mean connecting line on the box plot. Note that it is not the mean line, but the line connecting the means of each box. I have already calculated the mean. I need to implement this line on the box plot. I guess it should be using markLine, but I didn't try successfully.

我需要在箱线图上描绘均值连接线。注意不是均值线，而是各个箱子的均值连接起来的折线。我已经把均值计算出来了。我需要在箱线图上实现这条折线。我猜应该是用markLine，但是我并未尝试成功。

What does the proposed API look like?

Thanks
