FlexChart Update

By barneyb on January 14, 2008

Long time no blog…  I've updated my FlexChart component slightly, as well as repackaged it for easier consumption.  The new feature is the availability of a 'dataTipFunction' attribute on the root 'chart' element, which will be called to format data tips.  It gets passed an object with various keys about the backing chart item.  Since [...]

The Custom Tag Body-Scope

By barneyb on December 7, 2007

I was working with FlexChart a little this evening and ran into an interesting situation with a potentially very useful solution. I don't claim to be the first to think of it, but it's the first time I've used/seen it.
I added a date preparation tag a while back, but I thought it'd be nicer [...]

My Blog, My Rules

By barneyb on November 29, 2007

Charlie Arehart send me an email the other day  about my Flex charting control and the way it's presented on the site (which is poorly).  I ended up writing a fairly long response that was a bit tangential, but unreasonably so.  The basic premise was that it's my site, and I don't like maintaining web [...]

More Flex Chart Goodness

By barneyb on November 22, 2007

This evening, I extended my Flex charting widget further.  The demo is still available, and I've posted a new ZIP archive of the source.   Here's a quick rundown of what's changed:

The custom tag is now called xmlchart.cfm, instead of just chart.cfm.  That's to make way for a different chart.cfm that provides an XML-less interface (like [...]

My Flex-based Chart Engine

By barneyb on November 21, 2007

I've been looking for a good charting mechanism for a few personal apps.   CFCHART works in some cases, but I usually opt for SVG, either rendered inline (i.e. SVG and XHTML interleaved in an XML doc) or rasterized into a PNG server-side via Batik.  Both solutions have their merits, but both also have a lot [...]
