CuttingLine extracts a line from a structured data set and creates an 2D object. In general you will use the module Plot to display this object.
Name | Type | Description |
cutting_direction | Choice | You can choose the direction which should be variable. If you imagine a 2D-plot this corresponds to the values used on the x-axis. Therefore the data value at this point is displayed along the y-axis of the plot. More over you can enter a range of indexes on the chosen axis. The range begins at the corresponding index parameter and ends with the maximum index in this direction. |
i_index | Scalar | Constant index in x- direction or start of index range if cut along i is chosen. |
j_index | Scalar | Constant index in y- direction or start of index range if cut along j is chosen. |
k_index | Scalar | Constant index in z- direction or start of index range if cut along k is chosen. |

Name | Type | Description |
requiredmeshIn | UniformGrid RectilinearGrid StructuredGrid | Structured grid. |
requireddataIn | Float Vec3 | Data on structured grid points. The use of vector data is not implemented yet. |
Name | Type | Description |
outputdataOut | Unstructured_S2D_Data | Data on cutting line. |

With the module GenDat we create a simple structured data set. On the one hand we display
the data values on a cutting line by colors. Therefore we use the module FilterCrop
to extract one line out of the structured grid. You can see the resulting points and
their data values visualised by colors in the first image. To reproduce the same image
as shown in the example docu, use the draw option points in the renderer or insert the module
'Sphere' between ShowGrid and Collect to make points visible. More
over go to the Colormaps window in the information area of the renderer and click
on Collect_1_OUT to get the colormap displayed in your renderer window to see
the scaling.
One the other hand we use the module CuttingLine to dislay the same values as a 2D plot. The result is shown in the second image. On the x-axis of the plot you can find the used index range, here from zero to eight.
