我正在尝试实施the triangle example但它失败了d3 v4对我来说
triangles = [];
triangles.push({x : 250});
triangles.push({x : 350});
var group = svgContainer.append('g').attr('transform','translate('+ xOffset +','+ 30 +')');
var arc = d3.symbol().type('triangle');
var line = group.selectAll('path')
.data(triangles)
.enter()
.append('path')
.attr('d',arc)
.attr('fill','red')
.attr('stroke','#000')
.attr('stroke-width',1)
.attr('transform',function(d){ return "translate("+(d.x)+",0)"; });
错误:
未捕获的TypeError:type.apply(...)。draw不是函数
答案 0 :(得分:8)
而不是......
type("triangle")
......必须是:
type(d3.symbolTriangle)
以下是D3 v4.x中符号的the list。
以下是演示:
var svg = d3.select("svg");
triangles = [];
triangles.push({
x: 150
});
triangles.push({
x: 50
});
var arc = d3.symbol().type(d3.symbolTriangle);
var line = svg.selectAll('path')
.data(triangles)
.enter()
.append('path')
.attr('d', arc)
.attr('fill', 'red')
.attr('stroke', '#000')
.attr('stroke-width', 1)
.attr('transform', function(d) {
return "translate(" + d.x + ",30)";
});

旋转三角形的相同代码(如your comment中所述):
var svg = d3.select("svg");
triangles = [];
triangles.push({
x: 150
});
triangles.push({
x: 50
});
var arc = d3.symbol().type(d3.symbolTriangle);
var line = svg.selectAll('path')
.data(triangles)
.enter()
.append('path')
.attr('d', arc)
.attr('fill', 'red')
.attr('stroke', '#000')
.attr('stroke-width', 1)
.attr('transform', function(d) {
return "translate(" + d.x + ",30) rotate(180)";
});
