Quartz Composer Application

Chart                   A data application that uses a composition to render a 

                    3D bar chart through a QCView.

Sample Requirements         The project was created using the Xcode running under 

                    Mac OS X 10.6.x or later. The supplied Quartz Composer 

                    compositions were created using the Quartz Composer 

                    editor running under Mac OS X 10.6.x or later.

About the sample            The sample uses a Quartz Composer composition that draws 

                    3D chart according to the data given by the user. The data 

                    are stored in an array. Each entry in the array is a 

                    dictionary that contains label and value. The QC composition 

                    uses the iterator patch to draw the bar for each entry in 

                    the array. When the user modifies the data, the Quartz 

                    Composer composition re-render and update the chart.

Using the Sample            Open the project using the Xcode editor which can be 

                    found in /Developer/Applications. Build the project and run.
