Module traces

Object classes for recording and plotting time-series data.

This module defines a set of DataRecorder object types for recording time-series data, a set of Trace object types for specifying ways of generating 1D-vs-time traces from recorded data, and a TraceGroup object that will plot a set of traces on stacked, aligned axes.

Classes

[hide private]

DataRecorder
Record time-series data from a simulation.

InMemoryRecorder
A data recorder that stores all recorded data in memory.

Trace
A specification for generating 1D traces of data from recorded timeseries.

IdentityTrace
A Trace that returns the data, unmodified.

IndexTrace
A Trace that assumes that each data item is a sequence that can be indexed with a single integer, and traces the value of one indexed element.

SheetPositionTrace
A trace that assumes that the data are sheet activity matrices, and traces the value of a given (x,y) position on the sheet.

TraceGroup
A group of data traces to be plotted together.

ActivityMovie
An object encapsulating a series of movie frames displaying the value of one or more matrix-valued time-series contained in a DataRecorder object.

Functions

get_images(name, times, recorder, overlays=(0, 0, 0))
Get a time-sequence of matrix data from a DataRecorder variable and convert it to a sequence of images stored in Bitmap objects. source code

Function Details

[hide private]

get_images(name, times, recorder, overlays=`(`0`,` 0`,` 0`)`)

source code

Get a time-sequence of matrix data from a DataRecorder variable and convert it to a sequence of images stored in Bitmap objects.

Parameters: name is the name of the variable to be queried. times is a sequence of timepoints at which to query the variable. recorder is the data recorder. overlays is a tuple of matrices or scalars to be added to the red, green, and blue channels of the bitmaps respectively.
