I need to campare the data bettween to dates of my campaigns, like awords does in its dashboard but I don´t know if it is possible an if it's, how to achive this, I'm able to gt the dta of the last week etc, with the campaignPerformaceReport but I'm not sure if this report also provides the option to campare the data.
I want to perform this feature for ios Application.ç

Thanks.
