relxy

Description

Helper functions for specifying the 'radius' parameter in 'GlowMapper$map' and similar.

Usage

relx(r, mode = "data")

rely(r, mode = "data")

Arguments

r	Radius of point data relative to X or Y range of the plot, a value between 0 and 1.
mode	One of "data" (default) or "plot". Whether to use a radius relative to the extent of the data range or the plot range (which could have been adjusted manually).

Details

Helper functions for specifying the 'radius' parameter relative to the range of the plot as a proportion. I.e., a value of 0.02 corresponds to 2

Value

A class structure for input to 'GlowMapper$map'

Examples

gm <- GlowMapper$new(xdim=480, ydim=240, blend_mode = "additive", nthreads=4)

gm$map(x=1:10, y=runif(10)*100, radius=relx(0.01), intensity = 1)
pd <- gm$output_dataframe(saturation = 1)

ggplot() +
  geom_raster(data = pd, aes(x = x, y = y, fill = value), show.legend=FALSE) +
  coord_fixed(gm$aspect(), xlim = gm$xlim(), ylim = gm$ylim()) +
  scale_fill_gradientn(colors = additive_alpha(viridisLite::viridis(12))) +
  theme_night()

# Relative radius to y-range
gm$map(x=1:10, y=runif(10)*100, radius=rely(0.01))
pd <- gm$output_dataframe(saturation = 1)
ggplot() +
  geom_raster(data = pd, aes(x = x, y = y, fill = value), show.legend=FALSE) +
  coord_fixed(gm$aspect(), xlim = gm$xlim(), ylim = gm$ylim()) +
  scale_fill_gradientn(colors = additive_alpha(viridisLite::viridis(12))) +
  theme_night()
