Plotting and Analyzing Data in the GUI
Why Plot the Data Before Parameter Estimation
After you import the estimation data, as described in Importing Data into the GUI, it is useful
to remove outliers, smooth, detrend, or otherwise treat the data to
make it more tractable for analysis and estimation purposes. To view
and analyze the data characteristics, you must plot the data on a
time plot.

How To Plot Data in the GUI
To plot a data set, select the Data cell
that you want to plot in the Transient Data node
of the Control and Estimation Tools Manager GUI, and click Plot
Data.
The data is plotted on a time plot,
as shown in the next figure.
Using the time plot, you can examine
the data characteristics such as noise, outliers and portions of the
data to use for estimating parameters. After you analyze the data,
you the preprocess the data as described in Preprocessing Data in the GUI.
