you need to check the "Layout" tab of the "chart properties" dialogue for the objects on the page in the qvw document.
these can be set to Bottom, Normal, Top or Custom. If they are all set to Normal you would not get the reaction you are seeing. The settings are probably not coherent for the 4 charts you have on your screen. Adjust them and it will work as you want.
Thanks for your reply. I have checked the Lay out tab properties for all the charts presents in the qvw document which is set to 'Top'. When i opened this qvw document in Qlik view client the chart maxamization is working fine but when i am trying to open this through browser(Using qlik view server) and maxamize it, it is having the issue.
Please help me out are there any configuration settings need to do at Qlik view server level.
