NVD3 多轴条形图在绘图上重叠条形图
NVD3 Multiple Axis Barchart Overlapping Bars on Drawing
使用 nvd3 绘制多轴条形图。我的问题是条形重叠。在图表中，y 轴在左侧，另一个 y 轴在右侧。

两组数据绘制多图，但条形重叠。我的输出屏幕截图在这里。
唯一要做的就是调整条形的宽度和位置。这些可以通过 class
选择
d3.selectAll ('.bars1Wrap .nv-groups .nv-series-0 rect')
当我将轴切换到
testdata[1].yAxis = 1;
效果很好。
但问题是数据丢失的范围。我需要两个数据集的不同范围。
我尝试在绘制图表后调整条形的宽度
喜欢
var g3 = d3.selectAll ('.bars1Wrap .nv-groups .nv-series-0 rect')
.attr("width", function(d){ return d/2;});
但是没有成功...
任何帮助表示赞赏。
当然，nvd3 在 multiChart 上有问题，当您 select 为需要显示的两个可视化数据集键入 "bar" 时.
我要说的是，而不是这个
testdata[0].type = "bar";
testdata[0].yAxis = 1;
testdata[1].type = "bar";
testdata[1].yAxis = 2;
如果是
testdata[0].type = "line";
testdata[0].yAxis = 1;
testdata[1].type = "bar";
testdata[1].yAxis = 2;
它工作正常。
因此为了让两个条形图不堆叠。
需要做一些开箱即用的调整，调用此函数 post 图表已呈现。
function resetBarSize(d1){
//get the width of the bar, and make it half
var w2 = d3.select(".bars2Wrap .nv-bar").attr("width")/2;
if (!d1){
//initial load d1 will be undefined
//in that case make all the bars half
d3.selectAll(".bars1Wrap .nv-bar").style("width", w2);
d3.selectAll(".bars2Wrap .nv-bar").style("width", w2);
//translate the last bar so that there is no overlapping
d3.selectAll(".bars2Wrap .nv-bar")[0].forEach(function(d){
var t = d3.transform(d3.select(d).attr("transform")),
x = t.translate[0] + w2,
y = t.translate[1];
d3.select(d).attr("transform", "translate(" + x +"," + y + ")");
})
}else if (d1.yAxis ==2 && d1.disabled){
//in this case axis 2 is disabled or not visible so make bar1 width double.
d3.selectAll(".bars1Wrap .nv-bar").style("width", w2 *2);
}else if (d1.yAxis ==1 && d1.disabled){
//in this case axis 1 is disabled or not visible so make bar1 width double.
d3.selectAll(".bars2Wrap .nv-bar").style("width", w2 *2);
} else {
//in this case axis both axis is present. Make all the bars half and translate bar 2 so that they don't overlap.
d3.selectAll(".bars1Wrap .nv-bar").style("width", w2);
d3.selectAll(".bars2Wrap .nv-bar").style("width", w2);
d3.selectAll(".bars2Wrap .nv-bar")[0].forEach(function(d){
var t = d3.transform(d3.select(d).attr("transform")),
x = t.translate[0] + w2,
y = t.translate[1];
d3.select(d).attr("transform", "translate(" + x +"," + y + ")");
})
}
return;
}
现在在渲染图表后调用此函数。
nv.dispatch.on('render_end', function(newState) {
resetBarSize();
chart.legend.dispatch.on('legendClick', function(newState) {
chart.update();
setTimeout(function(){resetBarSize(newState)});
});
