Lollipop chart

Description

A Lollipop chart is a categorical chart that is basically a bar chart replaced by points being connected by a line to the zero-line of the reference axis representing the data. It can be helpful to reduce visual noise when all values have a similar height [1].

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.

src/Plotly.NET/ChartAPI/Chart2D.fs から始め、既存の Range chart と Chart.Bar の実装を読みます。スクリプトまたは notebook 環境で、ゼロから各データポイントまでをつないだ折れ線グラフを使用してプロトタイプを作成します。ライブラリの既存のチャートパターンに従い、#IConvertible をサポートするデータ入力を備えたトップレベルのロリポップチャート API があれば完了です。
