javascript - d3.js 热图未正确显示数据

标签 javascript d3.js svg

我有以下嵌入了 JavaScript 的 HTML 文档，我尝试在 d3.js 热图中绘制 JavaScript 对象列表。但它似乎只在每一行上重复显示第一行的数据。任何帮助将不胜感激。这是我的代码和输出:

这是我得到的输出。

最佳答案

我检查了你的代码，没有错误。这些值非常接近，您看不出差异。

但是您绝对可以通过改善色阶来改善这一点。而不是固定最小值和最大值。您可以从如下数据中找到它:

//构建色标 var myColor = d3.scaleLinear() .range(["#ffffff", "#c60606"]) .domain([d3.min(data, function(d) { return d.value}), d3.max(data, function(d) { return d.value})])

您将能够看到它们的颜色略有不同。我希望它能解决您的问题。
