There are basically four steps to generating charts: 
A] Create the chart model 
B] Bind the dataset(s) 
C] Build the chart 
D] Render the chart 
Which step are you having issue with?

Thanks for your inputs Ashwini ...

I have used the chart_faq to generate Bar and Line charts ..... but I am having issue with defining and biding the dataset for the gantt chart.

I have created a ganttDataSet with an array of GanttEnty values , but i am kind of confused with which data set should be bound to x axis and which one to y axis ....

I have tried using ganttDataSet with the y axis , and NumberDataSet for X axis but it gives me kind of weird chart .....

Could you advise me some thing here .....

Hi DevGulve,

Have you taken a look at the Chart Examples view within the BIRT Designer? It is available from the Eclipse menu at Window | Show View | Other... | Report and Chart Design. There are several different chart examples there. After you select one, you can open it and see all the code needed to generate that chart.
