legends orientation in ggvis

问题

In ggvis how to make legend vertical?

mtcars %>% ggvis(x = ~wt, y = ~mpg, fill = ~cyl) %>%
layer_points() %>%
add_legend("fill",properties = legend_props( legend = list(x = 500, y = 50)))

It puts the legends horizontally. I want it to be vertical.

Try the below code:

mtcars %>% ggvis(~wt, ~mpg, size = ~cyl, fill = ~cyl) %>% layer_points() %>% add_legend(c("size", "fill"))

Output chart:

Hope this helps.

Edit:

I explored the add_legend properties and unfortunately I do not see any way of achieving vertical continues scale legend using ggvis for now, however it can be achieved using ggplot2.

R code:

ggplot(mtcars, aes(wt, mpg, color = cyl))+geom_point()

Output chart:
