Visualize 2D Marker Data with Segments — visualise_2D_segment

This function visualizes marker data in a 2D plot (sagittal, frontal, or transverse plane) and draws lines between markers that belong to the same segment. The plot also supports adding a legend for the segments.

Usage

visualise_2D_segment_position(
  data,
  selected_frame,
  mapping_data,
  marker_col,
  segment,
  plane = "sagittal",
  point_size = 2,
  show_legend = TRUE
)

Arguments

data: A data frame containing the marker data (including columns for X, Y, Z positions).
selected_frame: An integer specifying the frame number to visualize.
mapping_data: A data frame that maps each marker to a segment.
marker_col: The column in `mapping_data` that contains the marker names.
segment: The name of the column in `mapping_data` that indicates the segment to which each marker belongs.
plane: A character string specifying the plane to plot. Options are "sagittal", "frontal", or "transverse". Default is "sagittal".
point_size: A numeric value specifying the size of the points in the plot. Default is 2.
show_legend: A logical indicating whether to show the legend. Default is TRUE.

Value

A ggplot2 object representing the 2D visualization of the marker data and segments.
