Method Details [hide private]

__init__(self, duration=10.0, yBounds=(0.0, 1.0), sampling=0.001, **kw)
(Constructor)

source code 

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:
  • duration - keep the x axis between (x_last - duration, x_last)
  • yBounds - (y_low, y_high)
  • sampling - interval between datapoints, in seconds
Overrides: object.__init__

add(self, arr)

source code 

add(yy) appends the y values from a numpy array. FUTURE: accept 2nd dimension (multi-series) Points beyond duration are removed onPlot.

get_data(self)

source code 

Returns a list of all visible datapoints.

Overrides: unreachable.GObject.get_data
