R: Layer lines on a plot.

layer_lines {ggvis} | R Documentation

## Layer lines on a plot.

### Description

`layer_lines` differs from `layer_paths` in that `layer_lines` sorts the data on the x variable, so the line will always proceed from left to right, whereas `layer_paths` will draw a line in whatever order appears in the data.

### Usage

    layer_lines(vis, ...)

### Arguments

`vis` | Visualisation to modify.
`...` | Visual properties.

### See Also

`layer_paths`

### Examples

    mtcars %>% ggvis(~wt, ~mpg, stroke = ~factor(cyl)) %>% layer_lines()

    # Equivalent to
    mtcars %>% ggvis(~wt, ~mpg, stroke = ~factor(cyl)) %>%
      group_by(cyl) %>% dplyr::arrange(wt) %>% layer_paths()
