Create ggplot axis styling theme arguments

Source: R/plot_axis.R
create_ggplot_axis_style.Rd

Creates ggplot2 theme arguments for axis borders and lines based on user inputs. This function handles axis styling through ggplot2 themes rather than plotly overlays, which provides better control especially when faceting is used.

Usage

create_ggplot_axis_style(input, isolate_fn = isolate)

Arguments

input

Shiny input object containing axis styling parameters.

isolate_fn

Function to use for isolating reactive values (default: isolate).

Value

A named list of ggplot2 theme arguments to be passed to theme_args parameter.

Details

When faceting is enabled, panel borders are always shown for the full plot. When faceting is disabled:

  • If both axis.showline and axis.mirror are TRUE: Full panel border

  • If only axis.showline is TRUE: Axis lines on x and y axes only

  • Otherwise: No borders

input <- list(
    axis.showline = TRUE, axis.mirror = TRUE,
    axis.linecolor = "black", axis.linewidth = 1
)
