Realtime Connection Monitor

You can visual weight matrices in realtime, using the PyGame package with the following class.

class brian.experimental.realtime_monitor.RealtimeConnectionMonitor(C, size=None, scaling='fast', wmin=None, wmax=None, clock=None, cmap=<matplotlib.colors.LinearSegmentedColormap object>)

Realtime monitoring of weight matrix

Short docs:

C

Connection to monitor

size

Dimensions (width, height) of output window, leave as None to use C.W.shape.

scaling

If output window dimensions are different to connection matrix, scaling is used, options are 'fast' for no interpolation, or 'smooth' for (slower) smooth interpolation.

wmin, wmax

Minimum and maximum weight matrix values, if left to None then the min/max of the weight matrix at each moment is used (and this scaling can change over time).

clock

Leave to None for an update every 100ms.

cmap

Colour map to use, black and white by default. Get other values from matplotlib.cm.*.

Note that this class uses PyGame and due to a limitation with pygame, there can be only one window using it. Other options are being considered.
