Plotting the time series
The hctsa package provides a simple means of plotting time series: the TS_PlotTimeSeries function.

Basic plotting

For example, to plot a set of time series that have not been assigned groups, we can run the following:
whatData = 'norm'; % Get data from HCTSA_N.mat
plotWhatTimeSeries = 'all'; % plot examples from all time series
plotHowMany = 10; % how many to plot
maxLength = 400; % maximum number of samples to plot for each time series
For our assorted set of time series, this produces the following:
Showing the first 400 samples of 10 selected time series, equally-spaced through the TimeSeries IDs in HCTSA_N.mat.

Freeform plotting

Many more custom plotting options are available by passing an options structure to TS_PlotTimeSeries, including the 'plotFreeForm' option which allows very many time series to be shown in a single plot (without the usual axis borders):
% Plot as a freeform plot without labeling time series:
plotOptions = struct('plotFreeForm',true,'displayTitles',false);
producing an overview picture of the first 300 samples of 40 time series (spaced through the rows of the data matrix).

Dealing with groups of time series

When the time series have been assigned groups (using TS_LabelGroups, here), this information is automatically incorporated into TS_PlotTimeSeries, which then plots a given number of each time series group, and colors them accordingly:
numPerGroup = 5; % plot this many examples of each group of time series
plotHow = 'grouped'; % plot examples of each assigned group of time series
In this case the two labeled groups of time series are recognized by the function: red (noisy), blue (no noise), and then 5 time series in each group are plotted, showing the first 500 samples of each time series.
