Leo Vasiliou: The Charts and Graphs of Web Performance

  • February 19, 2014 · 6:30 PM
  • Wayfair Offices - 4 Copley Place

Competitive benchmarks, forced ranks, change points, long-term trends, and SLAs -- various web performance assets.

Line charts, frequency distributions, cumulative distributions, heat maps, and scatter -- which one do I use?

Join us as we explore The Charts and Graphs of Web Performance!  We’ll first review some of the more well-known,  popular chart types and then build on them to discuss the power of the cumulative distribution for competitive benchmarks and forced ranking.

In the last Meetup, we looked at Heat Maps and some of the powerful ways to use them.  Now, we’ll introduce and show cumulative “hockey stick” charts:  how to create them, how to read them, how to use them and how to rank along them.

    Is there a parking on the building or nearby or street parking?

      Hi Sid, I usually park at The Colonnade Hotel Garage. It is on the other side of Huntington, down just a bit from the Meetup location.

    Looking forward to the meetup this evening, it's my first one as I just moved to Boston. I hope to learn more about web performance and how I can apply this to my own work!
