mahos.msgs.recorder_msgs.RecorderData

class mahos.msgs.recorder_msgs.RecorderData(params: dict | None = None, label: str = '')

Recorded multi-channel timeseries with channel/unit metadata.

Variables:

• units – Ordered (channel, unit) tuples defining recorded channels.

• data – Per-channel sample buffers aligned to xdata.

• xdata – Time-axis samples in seconds.

Call set_units() before appending measurement samples.

__init__(params: dict | None = None, label: str = '')

Methods

get_unit_to_channels()	Get a map from unit to list of corresponding channel.
get_units()	Get list of units.
get_xdata()	Get X-axis data for 2D plot.
get_ydata(ch)	Get Y-axis data for 2D plot.
has_data()	Return True if data is ready and valid data could be read out.
index(ch)	Get index of channel name (data label).
init_axes()	Initialize X and Y axes label, unit, and scale.
roll(data)	Roll data if the length of recorded data exceeds params["max_len"].
set_units(units)	set units and initialize data.
