In web application, user can customize page to show number of charts (developed using jasperreports) as per requirements. To utilize available space, we need to change size (height / width) dynamically of chart. I checked forums and found information about alter design as well other alternaive to load jasperdesign, make modifications, recompile and fill. I can not use alter design approach as Jasper API does not provide method to update height. I can change width / X,Y positions etc. So I tried Jasper design which is also not allowing me change chart element height in summary band. Is there a way to modify chart height? I appreciate immediate reply as I need to demo this to top management.
