GoCharts

GoCharts is a library to assist with building charts, by directly working with charting libraries, generating tabular data for Excel XLSX files and CSV files, or to transfer data to/from analytics solutions like Metabase and SimpleKPI.

It includes two sets of packages:

1. data structures to generically hold and manipulate different types of data
2. chart library helpers to make generating charts eaiser, often times using data structures mentioned above

Data Structures

Commonly used data structures include:

• Table - easy manipulation of tabular data including writing to CSV and XLSX.
• Time Series - for building time-based line charts and bar charts.
• Histogram - for building histograms and bar charts.

A full list is available in the data folder.
