New description:

 This is a feature request I would find extremely useful, and it's also one
 that would probably be a good one for GSoC, since it's a new feature with
 visually concrete results, which can make it more compelling/tractable for
 a new developer to get interested in.

 I maintain a continuous testing architecture for the Emscripten C++->JS
 compiler project (https://github.com/kripken/emscripten). It has an
 extensive unit testing and benchmarking suite, which prints a lot of
 graphable metrics out as the result of its run. The buildbot page is
 openly accessible at http://clb.demon.fi:8112/waterfall . More explanation
 at the bottom of the page here https://github.com/kripken/emscripten/wiki
 . While maintaining the buildbot, I've often wondered about the following:

   * How do build times vary over time? Are we optimizing the compiler, or
 is it getting more bloated and slowing down over time? Which commits
 caused big regressions/improvements?
   * How do buildbot task run times vary over time? These are already
 logged at the end of stdio with lines "program finished with exit code 0
 elapsedTime=1060.951319", which we'd like to graph over time.
   * How does runtime execution performance of compiled apps change over
 time? Emscripten has runtime benchmarks tester that tests runtime
 performance: http://clb.demon.fi:8112/builders/ubuntu-emcc-incoming-
 tests/builds/175/steps/Benchmarks/logs/stdio . Which commits caused big
 regressions/improvements?
   * How does compiled code size vary over time? There are some test apps
 that get built and stored after each commit: http://clb.demon.fi/dump/emcc
 /win-emcc-incoming-code-test/ . Which commits caused big
 regressions/improvements?

 To be able to measure these kind of quality concerns, visual graphing
 could be the answer. Being able to feed custom data fields into a data
 storage inside buildbot, and having a built-in data grapher integrated to
 buildbot HTTP server to visually compare metrics over time would be
 immensely helpful.

 The architecture should be somehow custom-driven so that the buildbot
 config files can control what data to generate and feed into graphs, since
 most of the above data points are specific to the project in question.

 Utilizing existing free graphing solutions would be expected, see for
 reference:
  * http://raphaeljs.com/analytics.html
  * https://www.reverserisk.com/ico/ (line graphs)
  * etc.
