jqplot tooltipContentEditor顯示錯誤x和y值

Question

我有此線jqplot線圖：使用tooltipContentEditor顯示懸停的點的x和y值

`var line = [[1,0.493], 
      [1,1.286], 
      [2,0.305], 
      [2,0.516], 
      [2,0.551], 
      [2,0.595], 
      [2,0.609], 
      [2,0.644], 
      [2,0.65], 
      [2,1.249], 
      [2,1.265], 
      [4,0.443], 
      [5,0.288], 
      [5,0.477], 
      [5,0.559], 
      [5,0.562], 
      [6,0.543], 
      [7,0.513], 
      [7,0.549], 
      [8,0.442], 
      [8,0.467], 
      [8,0.468], 
      [8,0.597], 
      [8,0.857]];` 

林。我需要顯示的值是確切的。

下面是使用代碼進口：http://jsfiddle.net/ZQh38/1/

問題：

1. 有時，所顯示的X和Y值是不正確的。例如，在（6，0.5）和（7，0.5）的最後一個點

2. 的值僅顯示帶1位小數，這需要是3

因此，問題是，我如何得到確切的y值？ 我也嘗試使用pointIndex，它與行中的值不匹配。

感謝您的幫助！

這裏是解決問題的方法：jsFiddle example

我更改了highlighter選項。

var Statistics = { 
    scatter: false,
