我想在R中更改剧情动画的速度。但是,该动画不是由剧情动画提供的默认播放按钮触发的。根据JS代码,它是通过单击Shiny action按钮触发的。在这种情况下,似乎没有考虑animation_opts()参数。
我尝试更改animation_opts()参数,例如“ frame”和“ transition”,但动画保持不变。我还尝试在javascript代码中更改这些参数,并且动画甚至无法开始。
library(shiny)
library(plotly)
library(htmlwidgets)
ui <- fluidPage(
actionButton("anim", "Animate"),
plotlyOutput("plot")
)
server <- function(input, output){
output[["plot"]] <- renderPlotly({
df <- data.frame(
x = c(1,2,1),
y = c(1,2,1),
f = c(1,2,3)
)
df %>%
plot_ly(
x = ~x,
y = ~y,
frame = ~f,
type = 'scatter',
mode = 'markers',
marker = list(size = 20),
showlegend = FALSE
) %>%
animation_opts(frame = 5000, transition = 4500, redraw = FALSE) %>%
animation_button(visible = FALSE) %>%
onRender("
function(el,x){
$('#anim').on('click', function(){Plotly.animate(el);});
}")
})
}
shinyApp(ui, server)
我想要一个用于绘制动画的帧和过渡持续时间的参数,并能够在代码中对其进行更改。

以下是设置这些选项的方法:
library(shiny)
library(plotly)
library(htmlwidgets)
ui <- fluidPage(
actionButton("anim", "Animate"),
plotlyOutput("plot")
)
server <- function(input, output){
output[["plot"]] <- renderPlotly({
df <- data.frame(
x = c(1,2,1),
y = c(1,2,1),
f = c(1,2,3)
)
df %>%
plot_ly(
x = ~x,
y = ~y,
frame = ~f,
type = 'scatter',
mode = 'markers',
marker = list(size = 20),
showlegend = FALSE
) %>%
# animation_opts(frame = 5000, transition = 4500, redraw = FALSE) %>%
animation_button(visible = FALSE) %>%
onRender("
function(el,x){
$('#anim').on('click', function(){
Plotly.animate(el,
null,
{
transition: {
duration: 2000,
easing: 'cubic-in-out'
},
frame: {
duration: 2000
}
}
);
});
}")
})
}
shinyApp(ui, server)
