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.

Comece em src/Plotly.NET/ChartAPI/Chart2D.fs lendo as implementações existentes de Range chart e Chart.Bar. Faça um protótipo em um ambiente de scripting ou notebook, usando gráficos de linhas conectados do zero a cada ponto de dados. Considera-se concluído quando houver uma API de gráfico lollipop de nível superior com uma entrada de dados que ofereça suporte a #IConvertible, seguindo os padrões de gráficos existentes da biblioteca.
