It changes the behaviour of the line chart slightly for the better, in terms of handling NULL values, allows multiple datasets with the Scatter chart (which are only really noticeable if you have lines enabled) and a few other minor things.
- Better handle NULL values in the line chart
- Multiple datasets are now permitted withe the Scatter chart

RGraph featured in JSmag

JSMag has an article in their July issue rounding up various graphing libraries, of which one of them is RGraph. And I think it fares rather well. In case you're wondering JSMag is an electronic (ie .pdf) magazine covering all things Javascript, and I've previously written for it (June issue - canvas article).

Mozilla Firefox 3.5 released
Web , HTML5

Months late (six I think) but well worth it, Mozilla Firefox 3.5 has finally been released. Lots of new things, including improvements to the canvas support, geolocation, private browsing, HTML5 video support and HTML5 audio support (to name but a few), which will surely help it maintain the title of number one browser available. Perhaps not the most popular, but that's slowly changing if the statistics I use are anything to go by. If anything, anyone who upgrades will be able to use my canvas based RGraph graphing software. I'd say that's reason enough alone to upgrade...

Javascript registry class using HTML5 DOM storage
Programming , Javascript , HTML5

This is a simple wrapper around the local and session storage API. It doesn't do anything special, it's just a nicer API.
| Storage type: | Name: | Value: | ||
|---|---|---|---|---|
You can get the code here.
Usage
// Create the registry, this can be "session" or "local" and defaults to "session" anyway.
settings = new Registry('session');
// Store something in the registry
settings.Set('name', 'value');
// Get it back from the registry
myVar = settings.Get('name');
Compatibility
With it being HTML5, only the following browsers are supported:
- Firefox 3.5
- Safari 4
- Internet Explorer 8 (!)
Update - 27th June 2009
Just read that if you want to find out what's in the storage areas, you can find that information out by using the "databases" option in Safaris introspection tool. Very useful.
