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.

Comienza en src/Plotly.NET/ChartAPI/Chart2D.fs leyendo las implementaciones existentes de Range chart y Chart.Bar. Crea un prototipo en un entorno de scripting o notebook, utilizando gráficos de líneas conectados desde cero hasta cada punto de datos. Se considera terminado cuando exista una API de gráficos de tipo lollipop de nivel superior con una entrada de datos que admita #IConvertible y siga los patrones de gráficos existentes de la biblioteca.
