d3js 时间线图 - 一个矩形块用于擦洗

【问题标题】：d3js timeline chart - with one rectangle block for a scrubd3js 时间线图 - 一个矩形块用于擦洗
【发布时间】：2020-05-01 11:34:24
【问题描述】：

我正在考虑创建一个底部只有一个矩形块的时间线图表。它被用作主洗涤器。

//当前 - http://jsfiddle.net/NYEaX/2427/

擦洗部分在哪里 - 我想要一个基本矩形。我应该对当前的代码库进行什么样的修改

所以它更像这样

最新的设计是这样的

随着洗涤器显示更多细节 - 例如 1 个月的日期范围 - 比例的格式变得更加详细

【问题讨论】：

  • 您好，我没有得到您想要执行的操作，您要从图表中删除“person p”部分吗？
  • 只有一个矩形 - 一个通用的滑动条 - 而不是主图表的迷你版
  • 赞这个jsfiddle.net/2mvhjr7z/2
  • 你的意思是去掉黄色和粉红色的条，保留一条细细的小线，就像提供的小提琴中的那条一样？
  • 是的——像这样——jsfiddle.net/KgomDr/46uLtcvf

标签： javascript jquery d3.js


【解决方案1】：

虽然我不清楚您到底想要实现什么，但我认为您需要有通用的基础矩形。

我删除了显示此基本矩形标签的代码行，并更新了迷你部分的高度。

如果这不是您所期望的，请告诉我。

请检查我的小提琴。

【讨论】：

  • 是的 - 类似这样 - 带有配置对象 - jsfiddle.net/KgomDr/46uLtcvf
  • 是什么意思？我的结果有什么问题？你能解释一下到底缺少什么吗？
  • 是的。这个有可能。您可以将日期存储为 date 对象而不是时间戳吗？
  • 好吧 - 我正在尝试根据可能的真实数据对其进行建模 - 时间戳/日期对象之间的转换有多容易 - 是否可以将其添加到配置对象中？
  • jsfiddle.net/m0czbuxs/2 -- 我已经将配置对象添加到 dom 中，所以它都在一个地方 -- 需要添加更多类以便在 css 中配置样式。我添加了更多数据以更接近实际数据结构 - 但带有洗涤器的迷你支架仍然错误地创建垂直线。我在这个版本上添加了一个工具提示 - jsfiddle.net/m0czbuxs/3
【解决方案2】：

从您的问题中不清楚您所说的 基本矩形 是什么意思，但是，您可以通过使用 .style("opacity", 0) 为您的每个元素将不透明度设置为 0 来隐藏您不想看到的任何内容'想隐藏如下（我几乎隐藏了所有内容，除了范围线，这是我对 基础矩形的最佳猜测）。您仍然可以像以前一样选择并擦洗它：
