Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I'm particularly interested in the zooming functionality which is done very well. Were these graphs generated using off the shelf software or were they coded from scratch?

This question came from our site for professional and enthusiast programmers.

I put a bounty on this question since there seems to be a different question/answer for every year, and there's no source for the provided answer. I'd personally like an official answer from an SE employee, but that is unlikely; I'd still like a source for the provided answer, and also an answer covering both graphs. – cybermonkey Jun 25 at 16:33

In the network profile reputation graph, they use Highcharts JS v2.2.0, as can be seen in the page source code.

When looking at the page source, it appears that Stack Exchange still uses Highcharts.js for their graphs (as of 26/06/2016).

However, they use different versions. Meta.SE uses v2.1.9 (see here), whereas the Network Profile uses v2.2.0 (see here).

This is proven by the source code of the reputation pages (both per-site and network):

Meta.SE reputation page:


script tag - highcharts.js

<body> (notice all of the highchart classes):

many classes such as highcharts-container and highcharts-grid

Network profile page:
