var w = 725;
var h = 500;
var padding = 20;
var svgcanvas = divElem.append("svg:svg")
.attr("width", w)
.attr("height", h);
,我希望限制該地區的路徑結束,但該元素已經消失試圖實現SVG:clipPath但幾乎是一片空白屏幕
svgcanvas.append("svg:clipPath")
.attr("id", "clipper")
.attr("d","M -200,0 A200,200 0 0,0 500,0 L -200,0")
.attr("transform", "translate(220,400) scale(1, -1)")
.style("stroke-width", 2)
.style("stroke", "steelblue")
.style("fill", "yellow");
不想行至超越這個路徑,但該元素已經消失
var myLine = svgcanvas.append("svg:line")
.attr("x1", 40)
.attr("y1", 50)
.attr("x2", 450)
.attr("y2", 150)
.attr("clip-path", "url(#clipper)")
.style("stroke", "rgb(6,120,155)");
不想圈子超越這條道路,但元素已經消失
var circle = svgcanvas.selectAll("circle").data(jsoncirclehigh);
circle.enter().append('circle')
.attr('opacity',0)
.attr("cursor","pointer")
.on("mouseover", function(){d3.select(this).style("fill", "red");})
.on("mouseout", function() {d3.select(this).style("fill", "orange");})
.attr("clip-path", "url(#clipper)")
.attr("cx", function(d) {return d.cx;})
.attr("cy", function(d) {return d.cy;});
