Question

我正在使用flot http://code.google.com/p/flot/並希望突出顯示系列中的特定欄，當用戶將鼠標懸停在鏈接上時，有誰知道該怎麼做？

乾杯，

你正在尋找的東西是highlight，這是記錄在API.txt：

highlight(series, datapoint) 

Highlight a specific datapoint in the data series. You can either 
specify the actual objects, e.g. if you got them from a 
"plotclick" event, or you can specify the indices, e.g. 
highlight(1, 3) to highlight the fourth point in the second series 
(remember, zero-based indexing). 

所以，你的代碼看起來是這樣的這個：

//before this, $.plot has been called and assigned to "plot" 
$('#mylink').mouseover(function(){ 
    plot.highlight(1,3); 
}).mouseout(function(){ 
    plot.unhighlight(1,3); 
});
