d3.js – 内联样式笔画宽度为粗体勾号

我期待{‘stroke-width’：’3px’}制作粗轴线.但它使得粗体轴标签.我希望文本被控制与字体相关的样式,如{‘font-style’：’normal’}.

使用“笔画宽度”有什么问题？我在Chrome和Firefox中都进行了测试.

这是我的代码：

<script>
    var margin = {top: 20,right: 10,bottom: 20,left: 40};
    var width = 960 - margin.left - margin.right;
    var height = 100 - margin.top - margin.bottom;

    var x = d3.scale.linear().range([0,width]);
    var y = d3.scale.linear().range([0,height]);
    var xAxis = d3.svg.axis().scale(x).orient("bottom");
          // .tickFormat(d3.time.format("%H:%M"));
    var yAxis = d3.svg.axis().scale(y).orient("left").ticks(height/10);

    var svg = d3.select("svg");
    var vis = svg.append("g")
        .attr("transform","translate(" + margin.left + "," + margin.top + ")")
        .style({'font-size': '10px','font-family': 'sans-serif','font-style': 'normal','font-variant': 'normal','font-weight': 'normal'});

    var redraw = function(selection,data,style) {
        selection.selectAll(".bar")
            .data(data)
          .enter().append("rect")
            .attr('class',"bar")
            .attr("x",function(d) { return x(d[0]) - .5; })
            .attr("y",function(d) { return y(d[1]); })
            .attr("width",5)
            .attr("height",function(d) { return height - y(d[1]);  })
            .style(style);

        vis.select(".x.axis").call(xAxis);
        vis.select(".y.axis").call(yAxis);
    };

    svg.attr("width",width + margin.left + margin.right)
        .attr("height",height + margin.top + margin.bottom);

    vis.append("g")
      .attr("class","x axis")
      .attr("transform","translate(0," + height + ")")
      .style({ 'stroke': 'Black','fill': 'none','stroke-width': '3px'})
      .call(xAxis);

    vis.append("g")
      .attr("class","y axis")
      .style({ 'stroke': 'Black','stroke-width': '3px'})
      .call(yAxis);

    // Now we draw the first barchart (we do not kNow about the 2nd one yet)
    var data1 = [[2,0.5],[4,0.8],[6,0.6],[8,0.7],[12,0.8]];
    x.domain([0,13]);
    y.domain([0.9,0]);

    vis.append("g")
      .attr("class","bar1");

    vis.select(".bar1")
      .call(redraw,data1,{'fill': 'Red','stroke': 'Black'});
</script>
