options(rmarkdown.html_vignette.check_title = FALSE) knitr::opts_chunk$set( collapse = TRUE, comment = "#>" )
Packages and data used below:
library(apexcharter) data("diamonds", package = "ggplot2")
You can set title, subtitle and axis' titles at once with ax_labs()
:
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_labs( title = "Cut distribution", subtitle = "Data from ggplot2", x = "Cut", y = "Count" )
If you want more control (font size, alignment, ...), you can use ax_title()
, ax_subtitle()
, ax_xaxis()
and ax_yaxis()
, as described below.
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_title(text = "Cut distribution")
You can set some options, for example:
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_title( text = "Cut distribution", align = "center", style = list(fontSize = "22px", fontWeight = 700) )
Full list of parameters is available here : https://apexcharts.com/docs/options/title/
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_title(text = "Cut distribution") %>% ax_subtitle(text = "Data from ggplot2")
With same options than for title:
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_title( text = "Cut distribution", align = "center", style = list(fontSize = "22px", fontWeight = 700) ) %>% ax_subtitle( text = "Data from ggplot2", align = "center", style = list(fontSize = "16px", fontWeight = 400, color = "#BDBDBD") )
Full list of parameters is available here : https://apexcharts.com/docs/options/subtitle/
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_yaxis(title = list(text = "Count")) %>% ax_xaxis(title = list(text = "Cut"))
With some options:
apex(data = diamonds, type = "column", mapping = aes(x = cut)) %>% ax_yaxis(title = list( text = "Count", style = list(fontSize = "14px", color = "#BDBDBD") )) %>% ax_xaxis(title = list( text = "Cut", style = list(fontSize = "14px", color = "#BDBDBD") ))
library(apexcharter) ## economics dataset from ggplot2 data("economics", package = "ggplot2") data("economics_long", package = "ggplot2") economics <- tail(economics, 50) economics_long <- subset(economics_long, date >= "2010-01-01")
Classic line:
apex(data = economics, type = "line", mapping = aes(x = date, y = uempmed))
Spline curve:
apex(data = economics, type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_stroke(curve = "smooth")
Steps chart:
apex(data = economics, type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_stroke(curve = "stepline")
Color line with gradient:
apex(data = economics, type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_fill( type = "gradient", gradient = list( shade = "dark", gradientToColors = list("#FDD835"), shadeIntensity = 1, type = "horizontal", opacityFrom = 1, opacityTo = 1, stops = c(0, 100, 100, 100) ) )
Solid area color:
apex(data = economics, type = "area", mapping = aes(x = date, y = uempmed)) %>% ax_fill(type = "solid", opacity = 1)
Line width:
apex(data = economics, type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_stroke(width = 1)
Dotted line
apex(data = economics, type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_stroke(dashArray = 6)
Add points to line :
apex(data = tail(economics, 20), type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_markers(size = 6)
Add labels over points
apex(data = tail(economics, 20), type = "line", mapping = aes(x = date, y = uempmed)) %>% ax_markers(size = 6) %>% ax_dataLabels(enabled = TRUE)
You can use vectors of parameters to custom series separately:
apex(data = economics_long, type = "line", mapping = aes(x = date, y = value01, group = variable)) %>% ax_yaxis(decimalsInFloat = 2) %>% ax_markers(size = c(3, 6)) %>% ax_stroke(width = c(1, 3))
apex(data = economics_long, type = "line", mapping = aes(x = date, y = value01, group = variable)) %>% ax_yaxis(decimalsInFloat = 2) %>% ax_stroke(dashArray = c(8, 5))
