我想在類中選擇一個路徑。選擇一個<path> d3.js
我想使用下面的代碼來選擇路徑,而不是選擇一行或所有行。我正在嘗試選擇「lines」類中的line class「line_series_2」,但我迄今爲止嘗試過的所有內容都不起作用。
這裏是小提琴: http://jsfiddle.net/zvkgs5s4/4/
//The data for our line
var lineData = [ { "x": 1, "y": 5}, { "x": 20, "y": 20},
{ "x": 40, "y": 10}, { "x": 60, "y": 40},
{ "x": 80, "y": 5}, { "x": 100, "y": 60}];
//The data for our line
var lineData2 = [ { "x": 20, "y": 25}, { "x": 90, "y": 20},
{ "x": 54, "y": 30}, { "x": 11, "y": 40},
{ "x": 23, "y": 32}, { "x": 10, "y": 60}];
//This is the accessor function we talked about above
var lineFunction = d3.svg.line()
.x(function(d) { return d.x; })
.y(function(d) { return d.y; })
.interpolate("linear");
var graph = d3.select('svg')
.append("svg:svg")
.attr("class", "line-graph")
.append("svg:g")
// append a group to contain all lines
var lines = graph.append("svg:g")
.attr("class", "lines");
lines.append("path")
.attr("class", "line_series_1")
.attr("d", lineFunction(lineData))
.attr("stroke", "blue")
.attr("stroke-width", 2)
.attr("fill", "none");
lines.append("path")
.attr("class", "line_series_2")
.attr("d", lineFunction(lineData2))
.attr("stroke", "red")
.attr("stroke-width", 2)
.attr("fill", "none");
d3.selectAll("g .lines .line_series_1").select("path").attr('stroke-width', '6');
下面的代碼將工作,但沒有選擇類 「的line_series_2」
d3.select("g .lines").select("path").attr('stroke-width', '6')
或
d3.selectAll("g .lines").select("path").attr('stroke-width', '6')
