Reverse time info in chart

[Ste]

Dear experts

My search

index="abc" search_name="xyz" Umgebung="prod" earliest=-7d@d latest=@d zbpIdentifier IN (454-594, 256-14455, 453-12232)
| bin span=1d _time aligntime=@d
| stats count as myCount by _time, zbpIdentifier
| eval _time=strftime(_time,"%Y %m %d") 
| chart values(myCount) over zbpIdentifier by _time limit=0 useother=f

produces the following chart:

For each zbpIdentifier I have a group within the graph showing the number of messages during several days. 

How to change the order of the day values within the group? Green (yesterday) should be the most left, followed by pink (the day before yesterday) and orange, .....

| reverse

will change the order of the whole groups, that's not what I need. 

All kind of time sorting like 

| sort +"_time"
or
| sort -"_time"

before and after 

| chart ...

 does not change anything.

Chart will put the columns in ascending order lexicographically. To get around this, you should use transpose, sort and transpose (back). Try something like this

| bin span=1d _time aligntime=@d
| stats count as myCount by _time, zbpIdentifier
| chart values(myCount) over zbpIdentifier by _time limit=0 useother=f
| transpose 0 column_name=date header_field=zbpIdentifier
| sort 0 -date
| eval date=strftime(date, "%Y %m %d")
| transpose 0 column_name==zbpIdentifier header_field=date

@ITWhisperer Cool, your proposal does exactly what I was looking for.
Thank you.
