Dumbbell plot

Description

Dumbbell plot [1] (also known as Dumbbell chart, Connected dot plot) is great for displaying changes between two points in time, two conditions or differences between two groups.

Example:

Pointers

• Ideally, you start prototyping in a scripting or notebook environment where you can iterate fast. installation instructions can be found here: https://plotly.net/#Installation
• Charts like this that are using baseline trace types to create a new chart type should only be implemented in the top-level Chart API. An example where this is already done is the Range chart that combines a set of differently styled line charts.
• When possible, use #IConvertible for data input, as this allows for strings, number types such as int and float, and DateTime.

從 src/Plotly.NET/ChartAPI/Chart2D.fs 開始，特別查看 issue 中引用的 Chart.Range 實作。按照 Plotly.NET 的安裝說明，在指令碼或 notebook 環境中製作圖表原型，並檢視基線折線圖是如何組合的。當提供支援彈性 #IConvertible 輸入的高階 Dumbbell 圖表 API，並顯示 issue 中描述的兩點連接時，即視為完成。
