Change axis direction

Question

How to change axis direction in ggvis plot?

For example, y-axis. I want an origin to be on left top of the graph (I already put my x-axis to the top by putting orient ="top").

data %>% 
  ggvis(~XX, ~YY) %>% 
  layer_points() %>% 
  add_axis("y", title = "Y title") %>% 
  add_axis("x", title = "X title", orient ="top")

Please share some code to illustrate what you're trying to achieve. — mtoto, Mar 23 '16 at 13:18
I want my y-axis to start at the left top and increase to the bottom (basically, to change y-axis direction) `data %>% ggvis(~XX, ~YY) %>% layer_points() %>% add_axis("y", title = "Y title")%>% add_axis("x", title = "X title", orient ="top")` — Olya, Mar 23 '16 at 13:24

I believe you need the scale_numeric argument with reverse = TRUE to flip the order of the range.

Below is an example based on the mtcars dataset.

library(ggvis)
mtcars %>% ggvis(~wt, ~mpg) %>%
  layer_points() %>%
  add_axis("x", orient = "top") %>%
  scale_numeric("y", reverse = TRUE)
