Chart of multiple sourcetypes

Hi,

I would like to get a line chart in which I can see a line for each trace level (verbose, info, warning, error). In addition I'd like to see on the same chart another line for the CPU Usage. It would let me know if errors are related to high CPU usage.

We have a sourcetype called "Trace" that contains the field "tracelevel". And we have a sourcetype called "CpuLoad" that contains the fields "Value" and "Counter". The "Counter" can be "ProcessorTime" or "UserTime".

I tried to combine the 2 queries into one line chart:

1. sourcetype="Trace" | timechart count by tracelevel
2. sourcetype="CpuLoad" Counter="ProcessorTime" | timechart avg(Value)

But I couldn't make it work.

Could you please assist?
