How to change column order created by chart

[halloweening]

I create a search:

...my search...
| chart values(duration) over TimeGap by Process

The table shows duration used by each process at specific time gap (t1,t2,t3..). It looks like:

TimeGap P3 P4 P1 P5 P2
t1
t2
t3
...

The column names (Pn) which are string-formatted field created by rex command mean different processes; they are sorted alphabetically with the chart command. How can I sort the Process by a specific sequence as P1 P2 P3 P4 P5?

If you are searching for alphabetical, just add this to the bottom:

... | table _* *

If you need a particular order, then spell it out like thi| makeresults

... | table _time P1 P2 P3 Etc and Whatever
