禁用d3刷子调整大小

问题描述

有可能有一个静态宽度的画笔，即不可调整大小的画笔？它仍然需要可拖动。

Is it possible to have a brush that is a static width ie a brush that is not resizable? It would still need to be draggable. There doesn't seem to be anything indicating whether it's possible in the documentation.

推荐答案

没有明确的选项，但所有你需要做的是在刷新事件处理程序中重置域，例如

There's no explicit option for that, but all you need to do is reset the domain in the brush event handler, for example

var brush = d3.svg.brush().on("brush", brushed);

function brushed() {
  brush.extent(desiredDomain);
}
