【问题描述】:
我有一个完全工作力有向图。
我正在尝试添加单选按钮,单击它们应该会根据条件动态更改节点的不透明度。
HTML
<style>
.links line {
stroke: #999;
stroke-opacity: 0.6;
}
.nodes circle {
stroke: #fff;
stroke-width: 1.5px;
}
.nodes circle {
stroke: #fff;
stroke-width: 1.5px;
}
div.tooltip {
position: absolute;
background-color: white;
max-width: 200px;
height: auto;
padding: 1px;
border-style: solid;
border-radius: 4px;
border-width: 1px;
box-shadow: 3px 3px 10px rgba(0, 0, 0, .5);
pointer-events: none;
}
</style>
<svg id="Network_graph" width="400" height="350"></svg>
<div id="map"></div>
<div id="legend">
<h3>Filter</h3>
<div class="input-group" id="filters">
<label>
<input type="radio" name="filter" value="All" checked="checked"> All</label>
<br />
<label>
<label>
<input type="radio" name="filter" value="Agent"> Agent</label>
<br />
<label>
<input type="radio" name="filter" value="Customer"> Customer</label>
<br />
<label>
<input type="radio" name="filter" value="Phone"> Phone</label>
<br />
<label>
<input type="radio" name="filter" value="ID_Card"> ID_Card </label>
</div>
</div>
</button>
我的 JSON 数据格式如下:
JSON
var IDData = JSON.stringify([
["node/105173", "node/38180995", "Agent", "Customer", "1379644.0", 1, 264, "1374903"],
["node/1061", "node/21373542", "Agent", "Customer", "530848.0", 1, 3000, "529502"],
["node/10750", "node/59648369", "Agent", "Customer", "1454228.0", 1, 120, "1454118"],
["node/10750", "node/78569210", "Agent", "Customer", "1425251.0", 1, 234, "1421416"],
["node/10750", "node/96726118", "Agent", "Customer", "1376239.0", 1, 434, "1376152"],
["node/10946829", "node/11190", "Customer", "Agent", "1409620.0", 20, 3380, "1406665"],
["node/10946829", "node/57774036", "Customer", "Customer", "1460029.0", 3, 960, "1459731"],
["node/109947", "node/97911872", "Agent", "Customer", "1323025.0", 1, 600, "1315582"],..])
使用这个函数,我将这个 JSON 数据转换成合适的格式来呈现图形,
$(document).ready(function() {
console.log(IDData);
var galData = JSON.parse(IDData);
var startnodes = [];
var endnodes = [];
var startnodetype = [];
var endnodetype = [];
var PayTime = [];
var TXN_COUNT = [];
var Total_Amt = [];
var SendTime = [];
galData.map(function(e, i) {
startnodes.push(e[0]);
endnodes.push(e[1]);
startnodetype.push(e[2]);
endnodetype.push(e[3]);
PayTime.push(e[4]);
TXN_COUNT.push(e[5]);
Total_Amt.push(e[6]);
SendTime.push(e[7]);
});
var final_data = createNodes(startnodes, endnodes, startnodetype, endnodetype, depth, PayTime, TXN_COUNT, Total_Amt, SendTime);
makeGraph("#Network_graph", final_data);
});
工作JsFiddle 就在这里。它的灵感来自d3.js library 这个例子。
所以,我的图表有 4 种类型的节点;代理,客户,电话,ID_Card。这些由
表示 d.type
所以,现在我在下面写了这段代码;应该根据被选中的单选按钮过滤图形,因此,例如,在单选按钮上选择值为“Agent”应该降低其他节点和链接的不透明度,除了那些从所有“代理”节点传出和传入的链接.
d3.selectAll("input[name=filter]").on("change", function(d){
var value = this.value;
node.style("opacity", 1);
link.style("opacity", 1);
if (value !== "all"){
value = +this.value;
node.filter(function(d){
return d.type != value;
})
.style("opacity", "0.5");
link.filter(function(d){
return d.source.type != value ||
d.target.type != value;
})
.style("opacity", "0.5");
}
});
似乎仍然缺少一些东西并且运行它并没有改变不透明度。我对 javascrpt 和 d3.js 很陌生,缺乏专业知识。所以,寻求帮助。
