valueTitle: Optional. The title of the x-axis.
valueTitleFontSize: The font size of the x-axis title if specified. Defaults to 14.
labelTitle: Optional. The title of the y-axis.
labelTitleFontSize: The font size of the y-axis title. Defaults to 14.
font: The font family of the text. Defaults to "Verdana, Geneva, Tahoma, sans-serif"

width: Optional. The width of the SVG output.
height: Optional. The height of the SVG output.

Value

A SVG horizontal bar chart.

Examples

library(ggplot2) # needed for the mpg data frame
library(dplyr) # needed for the data wrangling process

mpg %>% group_by(manufacturer) %>%
 summarise(median_hwy = median(hwy)) %>%
 horzBarChart(
   label = "manufacturer",
   value = "median_hwy",
   sort = "ascending"
 )
