```

## Examples

For an example that includes information about interfaces, see this example. To view the examples, refer to the location of the 'Install\_Path\\Motion\\Document\\Postprocessor API for Python.zip' file.

```python
# IOperationsSignalProcessingLineDataSeriesViewModel.py
import sys

# Get the current file's path and set the path for external modules.
current_dir = __file__.rsplit('\\', 1)[0]
external_modules_path = current_dir + '\\..\\..\\Modules'
sys.path.append(external_modules_path)

# Import necessary modules
from OperationAPI import *

# Start the headless application interface
applicationHandler = ApplicationHandler()

# Import result file
result_file_path = get_result_file_path()

# Set array about result file
filepaths = List[str]()
filepaths.Add(result_file_path)

# Open about result files
# This will open the result file in the application.
# When the result is first opened, a Page is created and an Animation View is created on that Page.
applicationHandler.AddDocument(filepaths)

# Get Active Page
# This retrieves the currently active page in the application.
page = applicationHandler.GetActivePage()

# Creating a Chart
# Create a new Chart View on the page
# This will create a new chart view with the specified name.
chartView = page.CreateChart("Chart")

# Set array about combination of characteristic and component
curvePaths = List[str]()
curvePaths.Add(r'Displacement/Magnitude')

# Create a PlotParameters object to specify the parameters for the plot.
# Set the Entity to Plot.
# The Target is the name of the target for which you want to retrieve the curves.
# Set the paths for the curves you want to retrieve.
# This is where you specify the characteristics and components you want to plot.
parameters = PlotParameters()
parameters.Paths = curvePaths
parameters.Target = "Crank"

# Add Curves (FilePath, Curve Parameter)
# FilePath - The path of the result to access.
# parameters - The class used as a parameter of the AddCurve function.
# The instance of the curve.
curves = chartView.AddCurves(result_file_path, parameters)

# Documentation Example
# Signal Processing
# SeriesName - A list of curve names.
# FilteringType - The types of the filter are as follows.
# Order - As decreasing value, output would be more smooth.
# Cut off Frequency(Hz) (Low Cut off Frequency(Hz)) - The value of frequency1.
# High Cut off Frequency(Hz) - The value of frequency2.
filtering = chartView.CreateFiltering(curves, FilteringType.LowPass, 2, 100, 100)
filtering[0].Order = 5

elif filtering[0].FilteringType == FilteringType.BandStop:
    filtering[0].LowCutOffFrequency = 200
    filtering[0].HighCutOffFrequency = 200

# Signal Processing - Smoothing
# SeriesName - A list of curve names.
# SmoothingType - The types of the sommthing are as follows.
# PointsOfWindow - The number of points for window.
# PolyOrder - The value of polyOrder.
smoothing = chartView.CreateSmoothing(curves, SmoothingType.MovingWindowAveraging, 2, 2)
if smoothing[0].SmoothingType == SmoothingType.MovingWindowAveraging:
    smoothing[0].PointsOfWindow = 4
elif smoothing[0].SmoothingType == SmoothingType.SavitzkyGloay:
    smoothing[0].PointsOfWindow = 4
    smoothing[0].PolynomialOrder = 3

# Signal Processing - FrequencyWeighting
# SeriesName - # SeriesName - A list of curve names.
# WeightingType - The types of the weighting are as follows.
# AxisType - The types of the axis are as follows. chartView.CreateFrequencyWeighting(series, WeightingType.AWeighting, FrequencyAxisType.X)
frequencyWeight = chartView.CreateFrequencyWeighting(curves, WeightingType.AWeighting, FrequencyAxisType.X)
frequencyWeight[0].WeightingType = WeightingType.BWeighting
frequencyWeight[0].FrequencyAxisType = FrequencyAxisType.Y

# Close the Pages
page.Close()

# Close the Document
applicationHandler.CloseDocument(result_file_path)
