Plot Line Graph for Multiple Series with Dynamic Y-axis Scaling

Generates a line graph for specified y variables over a shared x-axis, with dynamic scaling of the y-axis based on the data.

Usage

plot_line_graph(
  .data,
  x,
  y_vars,
  y_labels,
  title,
  y_axis_title,
  hline = NULL,
  hline_style = "dashed"
)

.data: A data frame containing the variables to plot.
x: The unquoted column name for the x-axis variable (e.g., year).
y_vars: A character vector of column names for the y variables to plot.
y_labels: A character vector of labels for the y variables (must match the length of y_vars).
title: The title of the plot.
y_axis_title: The title of the y-axis.
hline: An optional numeric value to draw a horizontal line.
hline_style: The line style for the horizontal line, default is "dashed".
