first thing i notice is that your data is not for the same timestamp. this means that the data will not stack as their x-values are different. if you want all data to for a given date to be stacked then you have to give them the same date (and time). the datagrouping only applies to highstock. your tooltip text can be formatted.

the cahrt is displayed correctl,y becasue you have stacked for the same x value, for for different, points are neighbours.
