Just 16 years ago we added the ChartDirector Plugin to our MBS Xojo Plugin collection.
Thanks to Mr. Jason J. Campbell for asking me to add a charts plugin and thanks to Peter Kwan from Advanced Software Engineering Limited for his support over the years and the excellent co-operation.
PS: ChartDirector is also the engine used by FileMaker Pro internally for the chart generation as you can see on the included DLLs.
