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).

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 [...]

Report/Query DSLs

By barneyb on January 5, 2008

I use a pair of stacked DSLs (Domain Specific Languages) for searching, reporting, and goal management in a couple applications. A discussion at work (with Joshua and Koen) provided the solution for the final piece I wanted to implement before releasing them. The first layer is for parsing query strings, and the latter [...]
