Plot distance-elevation profile with slope coloring

Creates a distance-elevation plot with segments colored by slope gradient.

Usage

plot_dz(
  d,
  z,
  fill = TRUE,
  horiz = FALSE,
  pal = NULL,
  ...,
  legend_position = "top",
  col = "black",
  cex = 0.9,
  bg = grDevices::rgb(1, 1, 1, 0.8),
  title = "Slope colors (percentage gradient)",
  brks = c(3, 6, 10, 20, 40, 100),
  seq_brks = NULL,
  ncol = 4
)

Arguments

d

Vector of cumulative distances

z

Vector of elevation values

fill

Logical, whether to fill segments with slope colors (default: TRUE)

horiz

Logical, whether legend should be horizontal (default: FALSE)

pal

Color palette for slope visualization (default: NULL, uses slopes_palette)

...

Additional arguments passed to graphics functions

legend_position

Position of legend (default: "top")

col

Color of the elevation profile line (default: "black")

cex

Character expansion factor for legend text (default: 0.9)

bg

Background color for legend (default: semi-transparent white)

title

Title for the legend (default: "Slope colors (percentage gradient)")

brks

Vector of slope break points for coloring (default: c(3, 6, 10, 20, 40, 100))

seq_brks

Sequence of breaks to show in legend (default: NULL, auto-generated)

ncol

Number of columns in legend (default: 4)

Value

NULL (creates plot as side effect)
