【问题描述】:
我正在制作一个 d3 图表并尝试在我的 rect 元素周围放置一个边框。 rect 元素附加到一个单元格,文本元素附加到同一个单元格。因此,如果我更改矩形中的笔画,我会由于某种原因丢失所有文本,如果我更改单元格中的笔画,边框和字体也会发生变化。
这是我绘制图表的部分代码。
this.svg = d3.select("#body").append("div")
.attr("class", "chart")
.style("position", "relative")
.style("width", (this.w +this.marginTree.left+this.marginTree.right) + "px")
.style("height", (this.h + this.marginTree.top + this.marginTree.bottom) + "px")
.style("left", this.marginTree.left +"px")
.style("top", this.marginTree.top + "px")
.append("svg:svg")
.attr("width", this.w)
.attr("height", this.h)
.append("svg:g")
.attr("transform", "translate(.5,.5)");
this.node = this.root = this.nestedJson;
var nodes = this.treemap.nodes(this.root)
.filter(function(d) { return !d.children; });
this.tip = d3.tip()
.attr('class', 'd3-tip')
.html(function(d) {
return "<span style='color:white'>" + (d.name+",\n "+d.size) + "</span>";
})
this.svg.call(this.tip);
var cell = this.svg.selectAll("g")
.data(nodes)
.enter().append("svg:g")
.attr("class", "cell")
.call(this.position)
.attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ")"; })
.on("click", function(d) { return this.zoom(this.node == d.parent ? this.root : d.parent); })
.style("border",'black');
var borderPath = this.svg.append("rect")
.attr("x", this.marginTree.left)
.attr("y", this.marginTree.top)
.attr("height", this.h - this.marginTree.top - this.marginTree.bottom )
.attr("width", this.w - this.marginTree.left - this.marginTree.right)
.style("stroke", 'darkgrey')
.style("fill", "none")
.style("stroke-width", '3px');
cell.append("svg:rect")
.attr("id", function(d,i) { return "rect-" + (i+1); })
.attr("class","highlighting2")
.attr("title", function(d) {return (d.name+", "+d.size);})
.attr("data-original-title", function(d) {return (d.name+",\n "+d.size);})
.attr("width", function(d) { return d.dx - 1; })
.attr("height", function(d) { return d.dy ; })
.on('mouseover', this.tip.show)
.on('mouseout', this.tip.hide)
.style("fill", function(d) {return coloring(d.color);});
cell.append("svg:text")
.attr("class", "treemap-text nameTexts")
.attr("id", function(d,i) { return "name-" + (i+1); })
.attr("x", cellMargin)
.attr("y", function(d) { return parseInt($('.treemap-text').css('font-size'))+cellMargin; })
.text(function(d) {return (d.name);});
cell.append("svg:text")
.attr("class", "treemap-text sizeTexts")
.attr("id", function(d,i) { return "size-" + (i+1); })
.attr("x", cellMargin)
.attr("y", function(d) { return 2*parseInt($('.treemap-text').css('font-size'))+2*cellMargin; })
.text(function(d) {return (d.size);});
此外,我考虑过在每个矩形元素周围创建线条并绘制四条线,但想知道是否有更简单的方法。谢谢。
