concept for analyzing and visualizing time series

[floweisshardt]

e.g. for

• path position/velocity/acceleration/jerks profiles
• joint position/velocity/acceleration/jerk profiles
• battery profile
• ...

currently the result data is limited to a single float (https://github.com/floweisshardt/atf/blob/master/atf_msgs/msg/MetricResult.msg#L4).
This could be used for plotting a time series this would need to be

recording and analyzing

• (prefered) add an optional time series field to all span metrics (e.g. tf_length_translation) additionally to the single float. data type needs to be a list of stamped floats
• frequency needs to be configurable in testblockset.yaml
  • none
  • either on each update step
  • fixed rate (trigger mechanism needed! interpolation needed?)
• can be expanded with fields for
  • min/max
  • avg/std_dev

visualization

• plot time series

series are introduced in #110
