ggvis: x-axis with whole number scale

Question

I want to get whole numbers for x-axis for ggvis plot.

MWE

df <- 
  structure(list(Factor = structure(c(1L, 2L, 3L, 1L, 2L, 3L, 1L, 
  2L, 3L, 1L, 2L, 3L), .Label = c("A", "B", "C"), class = "factor"), 
  X = c(15.5133333333333, 14.63, 14.41, 14.1266666666667, 13.1833333333333, 
  12.9466666666667, 13.6133333333333, 13.55, 13.5333333333333, 
  11.5566666666667, 11.3066666666667, 11.4566666666667), Y = c(20L, 
  20L, 20L, 40L, 40L, 40L, 70L, 70L, 70L, 100L, 100L, 100L)), .Names = c("Factor", 
  "X", "Y"), row.names = c(NA, -12L), class = "data.frame")

library(ggvis)

ggvis(data=df
      , x= ~X
      , y= ~Y
      , fill= ~Factor
      , stroke = ~Factor) %>% 
  arrange(Y) %>%
  group_by(Factor) %>%
  layer_points(shape=~Factor) %>% 
  layer_paths(fill := NA)  %>%
  add_axis('x', orient=c('bottom'), format='####')

One possibility is use values=seq(from=10, to=16, by=1) in add_axis(). But this is approach is not automated.

Maybe `seq(min(floor(df$X)),max(ceiling(df$X)),by=1)` then which is automated. — LyzandeR, Jan 14 '15 at 18:09
@MYaseen208 I'm not sure if this is what you are looking for, but `add_axis('x', orient=c('bottom'), format='d')` will use labels for *only* integer values, i.e. drop the in-between labels - here's the [`d3` reference](https://github.com/mbostock/d3/wiki/Formatting). — nrussell, Jan 14 '15 at 18:16
Thanks @LyzandeR and **nrussell** for your useful comments. `foramt='d'` is what I need for this `ggvis` graph. **nrussell** would you mind to change your comment to answer so that I can accept it. Thanks — MYaseen208, Jan 14 '15 at 18:49

Setting the format argument to 'd' will display only integer values in the axis label:

library(ggvis)
library(dplyr)
##
ggvis(data=df
      , x= ~X
      , y= ~Y
      , fill= ~Factor
      , stroke = ~Factor) %>% 
  arrange(Y) %>%
  group_by(Factor) %>%
  layer_points(shape=~Factor) %>% 
  layer_paths(fill := NA)  %>%
  add_axis('x', orient=c('bottom'), format='d')

More information on d3 formatting specifications is available on this page, as mentioned in the Common Properties section of this ggvis guide.
