Gantt Chart using Chart engine api

DevGulve

Hi,

I am trying to create a Gantt chart using chart engine api , even after banging my head over it I am not been successful in that .....

I am pretty new in chart designing using birt , can some body help me here.

There are basically four steps to generating charts:<br />
A] Create the chart model<br />
B] Bind the dataset(s)<br />
C] Build the chart<br />
D] Render the chart<br />
Which step are you having issue with? <br />
The following document answers frequently asked questions on how to use the Charting Engine API<br />

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.
