Activity chart graph

The chart graph contains graphical panels organized in vertical stacks. Chart panels are introduced specifically to explore the network activity by mouse interaction. The simulation produces two different types of data sets: Spike events (recorded by spike recorder) contain times and sender ids whereas analog signals contain continuous quantities from the recording devices (voltmeter or multimeter).

Analog signals

../../_images/activity-chart-graph-step-input.png

By default, it displays a line trace of the membrane potential.

../../_images/activity-chart-graph-noise.png

With noise input (noise generator), it shows noise behavior (fluctuation) of the membrane potentials and histogram of distributed values.

Spike activity

../../_images/activity-chart-graph-spike.png

By default, it displays a raster plot of the spike times as well as a time histogram of spikes.

../../_images/activity-chart-graph-spike-value-histogram.png

It displays a value histogram of the inter-spike intervals (ISI) as well as of the coefficients of variation of the ISI (CV of ISI) for the population.

../../_images/activity-chart-graph-spike-sender-histogram.png

It displays spike count, average Inter-spike interval (ISI) and coefficient of variation (CV of ISI) for each sender, e.g. neuron.
