Block that plots n time series.
To use this block, set the parameter n to the
number of time series that you like to plot.
Then, connect the signals for these time series to the input
port y.
There can be multiple instances of this block.
If they share the same value for fileName,
then they will add their plot to the same output file.
For convenience, we recommend to drag an instance of
Buildings.Utilities.Plotters.Configuration
at the top-level of your model. This instance can then
be used to globally set the fileName and
the samplePeriod for all plotters.
