The spiderweb plot created using the code below renders well within the Rstudio plot panel as shown below.
However, it appears as line plot when rendered using Shiny as below.
library(rCharts)
shinyServer(function(input,output){
output$plot <- renderChart2({
plot <- Highcharts$new()
table = data.frame(id = c("a1","g3","k5","y9","z11"),
value = c(252,345,421,189,236))
plot$chart(polar = TRUE, type = "line")
plot$xAxis(categories=table$id, tickmarkPlacement= 'on', lineWidth= 0)
plot$yAxis(gridLineInterpolation= 'polygon', lineWidth= 0, min= 0)
plot$series(data = toJSONArray2(table[,c("id","value")], json = F, names = F),
name = "Series", pointPlacement="on")
plot
})
})
HTML:
<head>
<script src="js/jquery.min.js"></script>
<link rel="stylesheet" href="shared/shiny.css" type="text/css" />
<script src="shared/shiny.js" type="text/javascript"></script>
<script src="js/highcharts.js" type="text/javascript"></script>
</head>
<body>
<div id="plot" class="shiny-html-output rChart highcharts" style="width: 4px; height: 60px"></div>
<body>
Any ideas to have the plot displayed in Shiny as it should be? The plot is rendered ok according to related post but the difference is that in my case the UI is built entirely using HTML while they use ui.R instead.
What is needed is to add
and it now works.
