ios - Problems with Core Plot Graph on device but not on simulator -
i'm trying use core plot create graph of 3 investment scenarios on ipad.
i'm using xcode 5, ipad 4, , ios 7.
the basic premise user enters initial investment , interest rate 3 different investments , upon clicking button, second view displayed shows core plot scatter plot representation of each scenario on same plot space.
my problem when run application on ipad (the actual device), resulting graph has plots equal y = 0 (this displayed, can't post pictures due need higher reputation stack overflow)
however, in ipad simulator in xcode graph appears properly, equations have set using data input initial data view.
i have 2 uiviews 2 separate view controllers. 1 data, , 1 graph display. code following:

} @end am missing something? why there difference between xcode ipad simulator graph , 1 displays on actual device? or advice welcome.
