Flotr Javascript Plotting Library

I’m proud to announce Flotr 0.1.0 alpha, a javascript plotting library based on the Prototype Javascript Framework (version 1.6.0.2 at the moment). This new (22kb) piece of javascript enables you to draw appealing graphs in most modern browsers. It replaces my older (and deprecated) plotting library Plotr. This time I took some more time to write documentation and examples, see the result on the Flotr project page.

Flotr is actually a rewrite of Flot (by Ole Laursen), a javascript plotting engine for jQuery. I (partially) rewrote it to use Prototype and added some new features like event hooks and mouse tracking.

Firing Custom Events With The Prototype Javascript Framework

Yesterday Sam Stephenson released the final version of the Prototype Javascript Framework. I’ve been using RC0 and RC1 for some time and what I was missing in earlier releases of Prototype’s the ability to fire custom events. I’m going to use it to fire events in Plotr. In this post I’ll explain how to fire custom events, and of course how to observe those events.

Efficient looping in Javascript

While I’m a great fan of Javascript Libraries like Prototype and Mootools, I’m less happy with their iterators. Iterating through a large array just takes ages using Array.each(). I think the most annoying thing with Javascript is that it freezes the browser while it’s being processed.

Porting Prototype Enumerable functions to Mootools Array objects

I really like the Prototype Framework and the functionality that comes with it, but I like Mootools even more because it’s so damn small and lightweight. Sometimes the minimalistic framework is just too light. Recently I needed some of Prototypes’ Enumerable functions for an Array but the app was implemented using Mootools.
