Is it possible to create a mixed column and line chart? Ideally, I'd like to create a chart with a couple of stacked columns and a trend line.
This is possible, see this post:

This is an old question, but for the sake of new readers.... this can be done in v6.
No, not possible at the moment.
Any idea if this is in the pipeline?
I don't think that this is possible in Splunk. It would be handy if it was though.
