sort() orders array elements with an optional comparison function. In a bar chart, descending order makes the largest and smallest values immediately visible. section 3.2.3
Use sort() to prepare measured data for visualization:
- Pass a comparison function that compares the count values of two technology objects. section 3.2.3
- For descending order, place the object with the greater count before the other. section 3.2.3
- Sort the data inside the Promise callback before passing it to the visualization-building function. section 3.2.3
data.sort((a, b) => b.count - a.count);
A focused implementation example sorts technology records by count in descending order. section 3.2.3
Sorting technology usage
data.sort((a, b) => b.count - a.count); places Excel, with 1,078, before Tableau, with 852, while Angular, with 20, appears last. section 3.2.3
