This document describes the enhancements in ChartDirector 6.3 compared to ChartDirector 6.2. For earlier versions of ChartDirector, please refer to the release notes archive.

ChartDirector 6.3 adds support for using embedded resources in executables. As embedded resources are mostly used in desktop GUI applications (as opposed to web or command line scripts), so ChartDirector 6.3 is only available for C++ and .NET (C#, VB). Desktop GUI applications commonly require a lot of images, such as for button and toolbar icons. To avoid having to distribute many images files with the application, many application frameworks have facilities to allow these contents to be embedded into the executable. These embedded contents are referred to as resources.

There are many different resource systems. Windows and MacOS have different resource systems. Some programming frameworks, such as Qt and .NET, have their own resource systems different from that of the operating system. ChartDirector can use images as background images, pattern colors, scatter symbols, CDML images, etc.. In previous versions of ChartDirector, these images have to be provided using file system paths. ChartDirector 6.3 supports "resource paths", allowing images to be loaded from resources.

Apart from images, ChartDirector 6.3 can also load fonts from resources.

• ChartDirector 6.3 adds support for arrow symbols in CDML images.
• For the ChartDirector MFC Chart Viewer, in previous versions of ChartDirector, if the mouse is used for zooming, clicking the mouse two times in rapidly succession will only trigger one zoom action. It is because the MFC treat the second click as a "double click" but not a "click" (no mouse down event generated). ChartDirector 6.3 now handles the double click as well and generates two zoom actions, allowing the user to zoom in faster. This is consistent with other GUI frameworks in which two clicks always generate two zoom actions.

ChartDirector 6.3 is designed to be compatible with earlier versions of ChartDirector, which means existing code should continue to run. ChartDirector 6.3 can coexist with earlier versions of ChartDirector. You can use multiple versions of ChartDirector on the same machine concurrently.
