Hope somebody can help me out because I can't find any reference about this error.

希望有人可以帮助我,因为我找不到有关此错误的任何参考。

I was working on this piece of code:

我正在处理这段代码:

var xMin = d3.min(data, function(d) { return d.value; });
var xMax = d3.max(data, function(d) { return d.value; });

if (0 > xMin & 0 > xMax) {
  xMax = 0;
}

if (0 < xMin & 0 < xMax) { 
  xMin = 0;
}

x.domain(xMin, xMax).nice();
y.domain(data.map(function(d) { return d.label; }));

but I must have made some mistake cause now the loading blocks with the error message below in the web console:

但我一定犯了一些错误,因为现在加载块在 Web 控制台中显示以下错误消息:

"TypeError: t.map is not a function @ http://d3js.org/d3.v3.min.js:2

“类型错误:t.map 不是函数 @ http://d3js.org/d3.v3.min.js:2

回答by Lars Kotthoff

.domain()takes an array as argument, i.e.

.domain()以数组作为参数,即

x.domain(xMin, xMax).nice();

should be

应该

x.domain([xMin, xMax]).nice();
