Hi, I want to generate a combined chart. My chart should plot both bar and line graph for same domain Axis and also it should have dual Axis.Iam attaching the sample graph that i need to generate. Your help will be appreciated greatly. <<chart.gif>> Thanks and Regards Gandhi,Raketla Software Engineer Digital Enterprise Solutions Honeywell > Honeywell Technology Solutions Lab > 151/1 Doraisanipalya, Bannerghatta Road, > Bangalore 560 076, INDIA > Phone: ++91-80-26588360(Extn :3244(Saturn)) > Fax : ++91-80-6584750 mobile : +91-80-31815880 This e-mail, and any attachments thereto, are intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
