Chart Expression show

[QSense]

İn my chart ,

I have two expression

one of them is quantity of request opening date more than 30 days : =Count({<ISTEK_ACISTARIHI2 = {"<=$(=Timestamp(Today() - 30, 'DD.MM.YYYY hh:mm:ss'))"},ISTEK_DURUM={'Açık'}>} ISTEK_ACISTARIHI2) 1 aydan uzun süredir Açık İstek Adedi

other expression is only quantity of requests : count(IF(ISTEK_DURUM='Açık',ISTEK_DURUM)) Açık İstek Adedi

but in chart "açık istek adedi" (Blue one)expression is shown for only 30 days How can I make it show through all dates like red expression

[QSense]

These two expressions are overlaped so I can not see one of them
