這是我的示例代碼來生成條形圖。當我點擊一個特定的列時,它應該導致另一個頁面。請幫助我。另一件事是如何讓圖表更具交互性並使用事件處理?如何將可視化添加到使用d3.js創建的圖表?

<!DOCTYPE html> 
<meta charset="utf-8"> 
<style> 

body { 
    font: 10px sans-serif; 
} 

.axis path, 
.axis line { 
    fill: none; 
    stroke: #000; 
    shape-rendering: crispEdges; 
} 

.bar { 
    fill: steelblue; 
} 

.x.axis path { 
    display: none; 
} 

</style> 
<body> 
<script src="http://d3js.org/d3.v3.min.js"></script> 
<script> 

var margin = {top: 20, right: 20, bottom: 30, left: 40}, 
    width = 960 - margin.left - margin.right, 
    height = 500 - margin.top - margin.bottom; 

var formatPercent = d3.format(".0%"); 

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

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

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

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

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 + ")"); 

d3.tsv("data.tsv", function(error, data) { 

    data.forEach(function(d) { 
    d.frequency = +d.frequency; 
    }); 

function mouseover(d, i) { 
    d3.select(rect[0][i]).style("fill", "red"); 
} 

    x.domain(data.map(function(d) { return d.letter; })); 
    y.domain([0, d3.max(data, function(d) { return d.frequency; })]); 

    svg.append("g") 
     .attr("class", "x axis") 
     .attr("transform", "translate(0," + height + ")") 
     .call(xAxis); 

    svg.append("g") 
     .attr("class", "y axis") 
     .call(yAxis) 
    .append("text") 
     .attr("transform", "rotate(-90)") 
     .attr("y", 6) 
     .attr("dy", ".71em") 
     .style("text-anchor", "end") 
     .text("Frequency"); 

    svg.selectAll(".bar") 
     .data(data) 
    .enter().append("rect") 
     .attr("class", "bar") 
     .attr("x", function(d) { return x(d.letter); }) 
     .attr("width", x.rangeBand()) 
     .attr("y", function(d) { return y(d.frequency); }) 
     .attr("height", function(d) { return height - y(d.frequency); }); 

}); 

</script>

在這兩種情況下,使用.on()功能描述in the d3 api

使A導航到一個新的頁面,附加一個「對()」方法,將您的列(矩形),使用事件處理程序像

.on("click", function(d,i) { 
     window.location.href='mynextPage'; 
}) 
+0

cmonkey,感謝您的建議。它真的對我有用。 :) – Konix 2013-02-19 16:37:35
