Detailed Description

Displays the firing of the neural networks either as emitted spike patterns or activity patterns in the layer. Used both for live simulation monitoring and for the play back of archived data. Different constructor is called depending on how it is being used.

void NetworkMonitor::setPointSize (   )  [private]
 

Use scaleFactorWidth to set point size appropriately. Since neuron groups could be rectangular, but vertexes are always square it is probably too much effort trying to make this perfect.
