D3：帶畫筆和縮放的單位條形圖（移調）

[英]D3: Unit Bar Chart with Brush and Zoom (transpose)

 原文  2017-08-22 20:50:26  6   1    javascript/ d3.js

問題描述

我試圖從塊https://bl.ocks.org/misanuk/fc39ecc400eed9a3300d807783ef7607換置條形圖，以更接近我自己需要的水平，但一直陷於使Y軸以相同的方式工作作為原始示例。 左Y軸應根據縮放和筆刷調整大小並移動，但是我嘗試執行的操作均保持不變。

任何指導表示贊賞。 這是代碼（只要在瀏覽器中加載了d3.v4，它就無需服務器即可工作）：

調用yAxis時，需要將類y軸而不是axis--y添加到組中
