Sorry, I said template but may be a utility function:


CreateAnaGraphs(Plot* plot, enum type) {
  for (auto& ana_event : audio_network_adaptation_events_) {
    if (ana_event.config.bitrate_bps) {
      float x = static_cast<float>(ana_event.timestamp - begin_time_) / 1000000;
      float y = 0;
      switch (type) {
        case BITRATE:
          y = static_cast<float>(*ana_event.config.bitrate_bps);
        case ...
      }
      plot->series_list_.back().points.emplace_back(x, y);
    }
 }
 plot->series_list_.back().style = LINE_DOT_GRAPH;
 plot->SetXAxis(0, call_duration_s_, "Time (s)", kLeftMargin, kRightMargin);
switch (xxx) {
 case BITRATE:
   plot->series_list_.back().label = "Audio encoder target bitrate";
   plot->SetSuggestedYAxis(0, 1, "Bitrate (bps)", kBottomMargin, kTopMargin);
   plot->SetTitle("Reported audio encoder target bitrate");
 case xxx
}
