PotD For The World

By barneyb on May 16, 2009

Last night was sort of the release of Pic of the Day (not safe for work, or my mom) into the wild.  The project is a couple months shy of five years old, and while I've talked about it obliquely all over the place, I've never really publicized it directly.  I'd made the assumption that [...]

The FlexChart Manifesto

By barneyb on October 22, 2008

The current state of web applications is a fragmented mess.  HTML is still the standard approach, but dynamic data loading with Ajax and application embedding with Flash are both incredibly popular, particularly for data-heavy applications.
HTML is great because it's easy to build and well understood by user agents, but you lack drawing capabilities.  SVG addressed [...]

FlexChart 2.0

By barneyb on October 20, 2008

I've released FlexChart 2.0 today.  Binary download is available here: flexchart_2-0-r4392.zip.  The demo app is still available, of course.  Backwards compatibility is not quite 100%, as I'll explain below, but the non-compatibilities only affect certain classes of charts, and they're the complex ones.  For simple stuff it should be drop-and-go.
There are no real outward changes [...]

More FlexChart Stuff

By barneyb on October 9, 2008

I've made another minor enhancement to FlexChart, this time around grouped legends.  Previously, if you mixed grouped series and ungrouped series (e.g. a stacked column chart with a line series overlaid), the legend would be all kinds of wonky for the line series.  I've fixed that so it'll now render in a reasonable way.
As always, [...]

FlexChart Update

By barneyb on September 30, 2008

Been a long while since I've made any updates to FlexChart, and this is only a minor one, but it's potentially important.  Since it's designed to be used in JavaScript applications, data tips and click events are all processed by JavaScript (not ActionScript).  When I'd created the data tip callbacks, I'd neglected to considered the [...]

FlexChart

FlexChart is a charting engine written in Flex that uses an XML descriptor to render charts dynamically at runtime. It's designed to be used from Ajax applications where the descriptor is supplied to the SWF dynamically, either generated client side or retrieved from the server.  Read the manifesto.  There is also a demo [...]

Projects

Here's a list of little projects that I maintain. This probably isn't complete, but as I update stuff, I'll add it here, so the list should keep growing.

Amazon S3 CFC – a little CFC for managing assets on Amazon's S3 service.
Amazon CloudFront CFC – a little CFC for signing URLs for Amazon's CloudFront service.

FlexChart Updates

By barneyb on April 29, 2008

The past month or so has seen quite a few improvements and bug fixes to FlexChart, though I haven't blogged about any of them.  Most notably, there was a weird NPE that manifested itself when loading a Pie chart via FlashVars.  For some unknown reason, Flex/Flash didn't give any indication the error was occurring, it just silently [...]

And Again!

By barneyb on January 18, 2008

Another update to FlexChart this evening, providing set and series colors (both fills and strokes), an option for including/excluding the legend when exporting a chart to PNG, and a few new examples showcasing the features (including some really ugly developer art).
With the coloring support, the 'Grouped Series' example makes a lot more visual sense, so [...]

More FlexCharts Goodness

By barneyb on January 17, 2008

Another batch of changes to FlexChart.
First is grouped series, which is hard to explain, but easy to understand.  Go hit the demo and select "Grouped Series" from the dropdown.  The chart layout has always been possible, but the legend just displayed a flat series list with no awareness of the groupings.  To see the old [...]
