我想爲簡單數據集製作堆疊條形圖(以下您可以找到代碼和數據)。使用d3-tip和CSS懸停效果與d3堆積條形圖

對於鼠標懸停的欄,我嘗試使用CSS懸停效果來更改欄的顏色(帶一類.bar的rect svg元素),並使用d3-tip顯示工具提示該酒吧所屬的地區名稱。

我遇到的問題是: 1 - CSS懸停效果根本不起作用。 (請在下面找到樣式表) 2 - 工具提示正在顯示,但僅當我將鼠標光標從欄下移動時纔會顯示。如果我從鼠標左/右/頂部移動鼠標光標,「mouseover」似乎沒有被檢測到。當它沒有被檢測到時,然而如果你點擊欄,它會被檢測到,並且工具提示會顯示。 3 - 工具提示應該顯示「d.State」(這是該地區的縮寫文本)的數據,但它給了我未定義的內容。 「d.State」與條形圖本身工作正常 - 軸蜱是使用這些數據創建的。

堆疊欄基於該一種製成:https://bl.ocks.org/mbostock/3886208

工具提示和懸停效果是基於這一個:http://bl.ocks.org/Caged/6476579

  1. 的CSS懸停效果是不工作的。(不是失蹤我猜?)

    的問題是使用D3它已經被填補。重寫它只需添加!重要的懸停填充

    填充:steelblue!important;

  2. 工具提示正在顯示,但只有當我將鼠標光標從欄下移動時纔會顯示。如果我將鼠標光標從左側/右側/頂部移動(我沒有面對任何問題?)

    我不確定問題到底是什麼,但是,我的猜測是,onmouseover只有當你徘徊時纔會起作用。因此,如果鼠標指針在生成之前已經在圖形上,它將不會顯示工具提示。

  3. 工具提示應該顯示「d.State」的數據。

    這裏的問題是狀態數據不附加到元素,即d.ages不包含狀態值。綁定數據時只需附加狀態值。

var margin = {top: 20, right: 20, bottom: 30, left: 40}, 
 
    width = 320 - margin.left - margin.right, 
 
    height = 320 - margin.top - margin.bottom; 
 

 
var x = d3.scale.ordinal() 
 
    .rangeRoundBands([0, width], .1); 
 

 
var y = d3.scale.linear() 
 
    .rangeRound([height, 0]); 
 

 
var color = d3.scale.ordinal() 
 
    .range(["#98abc5", "#7b6888", "#a05d56", "#ff8c00"]); 
 

 
var xAxis = d3.svg.axis() 
 
    .scale(x) 
 
    .orient("bottom"); 
 

 
var yAxis = d3.svg.axis() 
 
    .scale(y) 
 
    .orient("left") 
 
    .tickFormat(d3.format(".2s")); 
 

 
//define tooltip 
 
var tip = d3.tip() 
 
    .attr('class', 'd3-tip') 
 
    .offset([0, 0]) 
 
    .html(function(d) { 
 
    return "<strong>Region:</strong> <span style='color:red'>" + d.State + "</span>"; 
 
    }); 
 

 
var svg = d3.select("body").append("svg") 
 
    .attr("width", width + margin.left + margin.right) 
 
    .attr("height", height + margin.top + margin.bottom) 
 
    .append("g") 
 
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")"); 
 

 
//call tooltip 
 
svg.call(tip);

    if (error) throw error;

    data.forEach(function(d) {
