Namespace: [VM.Operations.Post.Interfaces](VM.Operations.Post.Interfaces.md)  
Assembly: VM.Operations.Post.dll

Defines the properties for a custom axis view model in an operations.

```csharp
public interface IOperationsCustomAxisViewModel : IOperationsAxisViewModelBase

```

#### Implements

[IOperationsAxisViewModelBase](VM.Operations.Post.Interfaces.IOperationsAxisViewModelBase.md)

## 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
# IOperationsCustomAxisViewModel.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 Background
axis = chartView.GetAxis("Y")
axis.LabelSize = 16
axis.LabelWeight = OperationAPIService.GetFontWeightFromString("Bold")
axis.FontColor = Colors.Red
axis.FontFace = FontFamily("Arial")
axis.Style = OperationAPIService.GetFontStyleFromString("Italic")

if axis.Default == False :
    axis.Decimal = 2
    axis.LabelFormatType = LabelFormatType.Number

if axis.IsAuto == False:
    axis.ScaleInterval = 5.0
    axis.ScaleMax = 100
    axis.ScaleMin = 10

axis.AxisType = AxisType.PositiveLogarithmic
if axis.AxisType == AxisType.PositiveLogarithmic:
    axis.LogarithmicBase = "10"

# Close the Pages
page.Close()

# Close Document
applicationHandler.CloseDocument(result_file_path)

```
