Zoho integration

Zoho integration

Hi.
Am working on zoho reports.I want to know can it possible to generate an empty graph without taking values from the data.Clearly i will explain you ----- I created an report by filtering X-axis and Y-axis, by taking two drop down options , It taking the default values and genenrating the graph but I want an empty graph to be generated first then after selecting the feilds from graph it should generate the related graph.
I hope you got my problem. Can you please help how to do it
Thanks in Advance.
