README
# litecharts4r
A lite wrapper around [echarts.js](https://echarts.apache.org/en/index.html) and [echarts4r](https://echarts4r.john-coene.com/).
## Install
```r
# install.packages("remotes")
remotes::install_github("the-y-company/litecharts4r")
```
## Examples
Use the lite API.
```r
litecharts4r() |>
set_title(title = "Hello world!") |>
set_x_axis(data = letters[1:20]) |>
set_y_axis() |>
add_serie(
name = "serie 1",
type = sample(c("line", "scatter"), 1),
data = runif(20)
) |>
add_serie(
name = "serie 2",
type = sample(c("line", "scatter"), 1),
data = runif(20)
)
```
Use an echarts4r object.
```r
data.frame(
x = 1:10,
y1 = runif(10),
y2 = runif(10)
) |>
e_charts(x = x) |>
e_line(y1) |>
e_scatter(y2) |>
as_litecharts4r()
```
## echarts4r vs. litecharts4r
The main difference with echarts4r is a more performant renderer that makes
for nicer visualisations transition, particularly using Shiny.
The latter also allows doing away with all the convoluted business of "proxies,"
making the use of the library far simpler.
```r
library(shiny)
library(echarts4r)
library(litecharts4r)
ui <- fluidPage(
theme = bslib::bs_theme(5L),
actionButton("render", "Render"),
div(
class = "row",
div(
class = "col-md-6",
litecharts4rOutput("lite")
),
div(
class = "col-md-6",
echarts4rOutput("ec")
)
)
)
server <- function(input, output, session){
output$lite <- renderLitecharts4r({
input$render
litecharts4r() |>
set_title(title = "Hello world!") |>
set_x_axis(data = letters[1:20]) |>
set_y_axis() |>
add_serie(
name = "serie 1",
type = sample(c("line", "scatter"), 1),
data = runif(20)
) |>
add_serie(
name = "serie 2",
type = sample(c("line", "scatter"), 1),
data = runif(20)
)
})
output$ec <- renderEcharts4r({
input$render
data.frame(
x = 1:10,
y1 = runif(10),
y2 = runif(10)
) |>
e_charts(x = x) |>
e_line(y1) |>
e_scatter(y2)
})
}
shinyApp(ui, server, options = list(port = 3000L))
```
