NVD3.js着色图中的特定条 [英] NVD3.js coloring specific bars in graph

问题描述

有办法为特定的酒吧着色吗？

Is there a way to color specific bars? If a bar is less than the line, color it red.

代码： https://github.com/tvinci/webs/blob/gh-pages/lineplusbar.html

示例： http://tvinci.github.io/webs/lineplusbar.html

我想这样做，但i的值不是我发送的y值。它已被修改：

I'd like to do something like this but the value for i is not the y value that I send in. It has been modified:

d3.selectAll("rect.nv-bar")
    .style("fill", function(d, i){
        return i > 50 ? "red":"blue";
    });

资料：

var overview_data=[
     {
        "key" : "Achieved",
        "bar": true,
        "values" : [ [ "1x" , 30] , [ "2x" , 70] , [ "3x" , 200] ]
     },
     {
        "key" : "Required",
        "values" : [ [ "1x" , 50] , [ "2x" , 100] , [ "3x" , 150] ]
     }
].map(function(series) {
    series.values = series.values.map(function(d) { return {x: d[0], y: d[1] } });
    return series;
});

推荐答案

您可以：

d3.selectAll("rect.nv-bar")
    .style("fill", function(d, i){
        return d.y > 50 ? "red":"blue";
    });
