Is it possible rename values when displayed on a chart?

I am trying to produce a query that represents a bunch of queries concatenated. My search is in a dashboard and looks like:

index=$index$ name=$name$ | eval min=round(min,3) | eval max=round(max,3) | chart values(min) as Min, values(max) as Max by path

When $name$ is specified, I get a chart over a range of 'paths' from 1->50. Each valid $name$ has 50 paths. If I set name=*, then I get conflicting values for each path (i.e., every $name$ has the same path names), so charting the results doesn't produce anything. I believe I could get around this if I could rename the paths to, for example, concatenate the names (e.g., path=name.path) - but I can't seem to get the query to cooperate. The ideal result is that the final chart resembles each of the individual charts concatenated together side by side.

Data is stored as comma delimited key=value pairs. E.g., name=my_test,path=1,min=3.917,max=5.232.

Any suggestions?

Much thanks!

This should work:

index=$index$ name=$name$ | eval min=round(min,3) | eval max=round(max,3)
| eval name_path = name ."_". path
| chart values(min) as Min, values(max) as Max by name_path

Ahh, thanks. I was trying to change the name after the chart, but this makes a lot more sense!

After a chart foo by path there is no name field left to use 😛
