get_time_axis: Manually draw an x-axis

In Yutong441/TBdev: Infer a Trophoblast Developmental Trajectory

Description

Sometimes you may want to put the x axis in certain locations other than the periphery of the plot as in the default ggplot option. Here I only implemented the version for x axis but it would be trivial for y axis as well. The underlying rationale is simple. Draw the axis and put on the labels.

Usage

get_time_axis(
  min_x,
  max_x,
  x_name,
  AP,
  y_level = 0,
  shorten_ratio = 0.85,
  ticks_df = NULL,
  tick_height = 0.005
)

Arguments

min_x	where to draw the x axis from
max_x	where the axis ends
x_name	name for the x axis
AP	aesthetic paameters
y_level	which y coordinate
shorten_ratio	shorten the x axis from max_x. This is because sometimes the axis tip is cut off from the edge of the plot.
ticks_df	a dataframe for plotting the axis ticks

Value

a list of ggplot layers, must contain a column called x for the locations of the ticks and the labels to put on
