Join Multiple Fields to Form Label

I have the following field in my log event. I can plot max, min, avg, etc for the mb, me, and md fields. However, the X-axis shows only the selected field, in my case, it is "method", so the X-Axis would show "myMethod1", "myMethod2", etc.

Would it be possible to have the label set to"myClass.myMethod1", "myClass.myMethod2" ?

"source": {
"class": "myClass",
"method": "myMethod1",
"line": 100,
"mb": 1442764831153,
"me": 1442764831153,
"md": 23
}

"source": {
"class": "myClass",
"method": "myMethod2",
"line": 100,
"mb": 1442764831153,
"me": 1442764831153,
"md": 23
}

Thanks...

Not currently, I think that's coming in 4.2.

If you're looking for customizable axis labels, this is still on the roadmap for a future release. Please feel free to comment with your use case or +1:
