Hi @Anonymous :
If you want to put leave & Total work hrs in the same series, then you must transpose the data source table. But PowerApps currently does not have a transpose function, so you have to reconstruct the data source.For example:
Table(
{Type:"Total working hrs",'10/11/20':LookUp(SPlist,Date="10/11/20").'Total working hrs','10/12/20':LookUp(SPlist,Date="10/12/20").'Total working hrs','10/13/20':LookUp(SPlist,Date="10/13/20").'Total working hrs','10/14/20':LookUp(SPlist,Date="10/14/20").'Total working hrs','10/15/20':LookUp(SPlist,Date="10/15/20").'Total working hrs'},
{Type:"Leave",'10/11/20':LookUp(SPlist,Date="10/11/20").Leave,'10/12/20':LookUp(SPlist,Date="10/12/20").Leave,'10/13/20':LookUp(SPlist,Date="10/13/20").Leave,'10/14/20':LookUp(SPlist,Date="10/14/20").Leave,'10/15/20':LookUp(SPlist,Date="10/15/20").Leave}
)

But this is very troublesome, I don’t recommend you to do this.
