I have three variables, Temperature, Index and Using_Time, Temperature is a continuous value. Index is an integer, like 1,2,3,4....Using_time is also a continuous value. In graph builder, I put Temperature in y axis, Index in Group X and Using_time in Group Y to see the distribution of Temperature at different Index range and Using_Time range. Jmp devides index and using_time automatically. I can only define the number of levels of Group Y and Group X but can not change the grouping method, like between which value to which value is a group. Can I define the Group myself? Thanks.
Currently, I use a new column to mark the group I want. But because I need to try different grouping method, I need keep updating this column which cost me much time.
