Defined in:
lib/strava/models/stream_set.rb

Overview

Represents a collection of activity streams from the Strava API.

A StreamSet is returned when requesting activity or segment effort streams and contains multiple synchronized time-series data streams. Each stream contains data points that correspond to the same moments in time or distance.

Examples:

Fetching and analyzing multiple streams

streams = client.activity_streams(1234567890,
  keys: 'time,distance,heartrate,watts',
  key_by_type: true
)

# Access individual streams
time_data = streams.time.data           # Array of elapsed seconds
hr_data = streams.heartrate.data        # Array of heart rate values
power_data = streams.watts.data         # Array of power values

# Calculate average power for time above threshold HR
threshold_hr = 160
time_data.each_with_index do |time, i|
  if hr_data[i] > threshold_hr
    puts "At #{time}s: HR=#{hr_data[i]}, Power=#{power_data[i]}W"
  end
end
