Flamegraph option is error.

[SpringMT]

I try to use stackprof.
I can show text summary of stackprof results, however not show flamegraph(using --flamegraph option) occuring errors.

Errors is below.

% bundle exec stackprof tmp/stackprof-cpu-sample.dump --flamegraph
/Users/foo/bar/vendor/bundle/ruby/2.1.0/gems/stackprof-0.2.7/lib/stackprof/report.rb:83:in `print_flamegraph': profile does not include raw samples (RuntimeError)
    from /Users/foo/bar/vendor/bundle/ruby/2.1.0/gems/stackprof-0.2.7/bin/stackprof:60:in `<top (required)>'

    from /Users/foo/bar/vendor/bundle/ruby/2.1.0/bin/stackprof:23:in `<main>'

Text summary is below(success).

% bundle exec stackprof tmp/stackprof-cpu-sample.dump --limit 1

Flamegraphs require more data to draw so you must run StackProf.start(raw: true). I forgot to document this in the readme.

Thx!
I can see a FlameGraph!

Only for Japanese, I wrote the blog for stackprof.
