Highcharter Demos

This repository contains demonstrations of the highcharter package for R.

highcharter is a wrapper for the Highcharts JavaScript library.

Overview

The demos are Quarto documents showcasing charts created with various methods:

• highchartzero(). This function creates a Highchart chart using htmlwidgets. The accessibility module can be added as a dependency with this chart.
• hcmap(). This creates a map from Highmaps - Map Collection.
• highchart(type = "stock"). This function creates a Highchart stock chart using htmlwidgets.

Each demo shows a data visualization using one of the methods above. The general pattern is to:

1. Load the necessary R packages.

2. Build, import, or read data.

3. Set accessibility options using options() for the chart.

4. Set the Highcharts version 11 color palette.

5. Visualize the chart.

How to Use the Demos

Organization

The demos are organized in Quarto Documents.

The repository is organized into folders for each of the Highcharts libraries:

• highcharts-core contains demos of the Highcharts Core library
• highcharts-maps contains demos of the Highcharts Maps library
• highcharts-stock contains demos of the Highcharts Stock library
• highcharts-gantt contains demos of the Highcharts Gantt library

In each folder, there are sub-folders grouping demos by category. For example:

• highcharts-core/line-charts folder contains Quarto Documents that demonstrate line chart functionality.
• highcharts-core/line-charts/data-raw folder contains R scripts for downloading data files.
• highcharts-core/line-charts/data folder contains downloaded data files.

The Boost module is an advanced chart feature for rendering large amounts of data points and series:

• boost-module folder contains demos of the Boost module with R scripts.
