我找到了一个示例here,它与我想做的完全匹配。
唯一的问题是我不知道将代码放置在R仪表板脚本中的位置。主持人说他做错了:代码必须放在plot $ series(event = ...)中,但是我可以在哪里放置plot $ series(event = ...)?
我尝试将其放在jsCode(程序包Shinyjs)的开头,但没有任何反应。我也在ui中尝试过...
library(highcharter)
library('shinyjs')
data_plot <- data.frame(categories = c("A", "B", "C", "D"),
serie1 = c(1563, 1458, 205, 695),
serie2 = c(562, 258, 17, 115),
serie3 = c(324, 654, 23, 987),
serie4 = c(123, 567, 234, 12),
serie5 = c(376, 88, 98, 123)
)
jsCode <- "
plot$series(event = legendItemClick = #! function(event) {
if (!this.visible )
return false;
var seriesIndex = this.index;
var series = this.chart.series;
for (var i = 0; i < series.length; i++)
{
if (series[i].index != seriesIndex)
{
series[i].visible ?
series[i].hide() :
series[i].show();
}
}
return false;
} !#)"
ui <- dashboardPage(
dashboardHeader(title = "My Dashboard"),
dashboardSidebar(),
dashboardBody(highchartOutput ("hc1")))
server <- function(input, output,session) {
#Normal Chart
output$hc1 <- renderHighchart ({
Hch <- highchart(hcaes(x = Spring ,y = Ponctuation)) %>%
hc_title(text = "Graph",
margin = 20, align = "left",
style = list(color = "#FE8000", useHTML = TRUE)) %>%
hc_xAxis(categories = data_plot$categories, title = list(text = "Number
of spring",color = "#FE8000")) %>%
hc_yAxis(title = list(text = "Result", color = "#FE8000"))%>%
hc_add_series(name = 'serie1', data = data_plot$serie1) %>%
hc_add_series(name = 'serie2', data = data_plot$serie2)%>%
hc_add_series(name = 'serie3', data = data_plot$serie3)%>%
hc_add_series(name = 'serie4', data = data_plot$serie4)%>%
hc_add_series(name = 'serie5', data = data_plot$serie5)
Hch})
}
shinyApp(ui, server)
编辑
我更改了上面的jsCode,但这不起作用:
hc1$series(legendItemClick = function(event) {
if (!this.visible )
return false;
var seriesIndex = this.index;
var series = this.chart.series;
for (var i = 0; i < series.length; i++)
{
if (series[i].index != seriesIndex)
{
series[i].visible ?
series[i].hide() :
series[i].show();
}
}
return false;
})
答案 0 :(得分:1)
更新:
在这种情况下,我们真的不需要shinyjs
,因为必须将js
代码作为参数值传递给函数hc_plotOptions()
,如上一个问题中提到的那样为event
的值。
