问题描述
Works
我通过d3js生成svg路径。或者 data()
+ mesh()
或 datum()
+ mesh()
work。
svg.append(g ).attr(id,border)
.attr(style,fill:none; stroke:#646464;)
.selectAll(path)
.data([topojson.mesh(json,L0,function(a,b){return a!== b;})))
.enter()。append(path)
.attr(d,路径);
或:
//内陆边界线
svg.append(g)。attr(id,coast)
.attr(style,fill:none; stroke :#646464;)
.append(path)
.datum(topojson.mesh(json,json.objects.admin_0,function(a,b){return a === b; }))
.attr(d,path);
$ b

添加 stroke-dasharray:8,4
导致:
更改为 stroke-dasharray:6,3 ,3,3
导致:
编辑:好的。首先,由于topojson.mesh()总是返回一个单一的MultiLineString,而这又反过来产生一个单一的路径,但是为什么dasharray:none工作正常!
有什么想法?我认为这些dasharray会使部分路径未关闭。 (检查正在进行)。

I generate svg paths via d3js. Either data()
+ mesh()
or datum()
+ mesh()
work.
svg.append("g").attr("id","border")
.attr("style", "fill: none; stroke:#646464;")
.selectAll("path")
.data([topojson.mesh(json, L0, function(a, b) { return a !== b; })])
.enter().append("path")
.attr("d", path);
or :
//inland borders lines
svg.append("g").attr("id","coast")
.attr("style", "fill: none; stroke:#646464;")
.append("path")
.datum(topojson.mesh(json, json.objects.admin_0, function(a,b){return a===b;}))
.attr("d", path);
Breaks
Adding stroke-dasharray: 8,4
result into:
Changing it to stroke-dasharray: 6,3,3,3
result into:
Some artifacts appears, and half of the strokes are missing/invisible (borders with Ind/Pakistan, Ind/Nepal, Ind/Myamar, Myamar/Cambodia). If I add a similar stroke-dasharray to the coastline generation, same mess appear with blue lines.
Edit: Ok. First, i'am squizzed because the topojson.mesh() always return a single MultiLineString which, in turn, generate a single path. But why is it that the "dasharray:none" works fine !??
Any idea ? I think these dasharray makes a portions of the path not closed. (check up ongoing).
