In the following example, the data is one year's worth of measurements of the outdoor temperatures in Augsburg, with four samples taken per hour. Assuming that the chosen time division is related to the events, it is also easy to recognize global and local patterns, such as recurrent events. Temporal raster plots make it easy to show time-based relations within a large sets of time-interval data and often make it easy to recognize local maxima and minima. Spiketimes are hashed by the trial length. When visualized, particularly the color-coded variant of the plot may easily show a carpet-like pattern. RASTERPLOT (T,N,L) Plots the rasters of spiketimes (T in samples) for N trials, each of length L samples, Sampling rate 1kHz. True, but then you spend another 10 lines of code trying to make it not look like complete crap.

In the 3D variant of the plot, it is often coded as a height. Raster plots and MATLAB Posted in Software A colleague once told me: in MATLAB, drawing a raster plot is a trivial, one line command. In a 2D plot, the value to be plotted is coded with an intensity or a color.
A common example would be that one axis shows hours in a day, the other days in a year. Temporal raster plots are also sometimes referred to as carpet plots.Įach occurrence is registered in a Cartesian coordinate system, in which both axes show time, have different time resolutions: one axis shows slices of data, the other some sensible interval. A temporal raster plot is a graphic representation of occurrences in a certain temporal relation.
