带有 rCharts 的 Highcharts 3D

Question

rCharts可以和Highcharts的3D模块一起使用吗？以下是 Highcharts 3D 的示例：

http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/3d-scatter-draggable/

错误

下面我的示例代码出现的错误是：

Error in envRefInferField(x, what, getClass(class(x)), selfEnv) : ‘zAxis’ is not a valid field or method name for reference class “Highcharts”

示例代码

这是我使用的示例代码：

library(rCharts)

# Based on example from: http://jsfiddle.net/highcharts/V37Vv/light/
plotData <- data.frame(x = c(1,1,1,2,2,4,4,7,7,8), 
                       y = c(1,1,1,3,6,5,2,1,1,1), 
                       z = c(1,2,5,2,4,7,8,3,5,5), 
                       category=rep(c("A", "B"), 5), stringsAsFactors=FALSE)

xLabel <- "X" 
yLabel <- "Y" 
zLabel <- "Z" 
title <- "Title"

if (is.null(rownames(plotData))){
    rownames(plotData) <- as.character(1:nrow(plotData))
}

# HighCharts point name
plotData$name <- rownames(plotData)

# Scatter plot
h1 <- rCharts::Highcharts$new()
h1$setLib("libraries/widgets/highcharts")

h1$chart(renderTo="container",
         margin=c(150, 75, 75, 75),
         type='scatter',
         options3d=list(enabled=TRUE,
                        alpha=20,
                        beta=30,
                        depth=200))

h1$title(text=title)
h1$xAxis(title=list(enabled=TRUE, text=xLabel))
h1$yAxis(title=list(enabled=TRUE, text=yLabel))
h1$zAxis(title=list(enabled=TRUE, text=zLabel))

# Divide the dataset, split by category and put into list() format
# From: http://rcharts.io/viewer/?5735146#.VF6NS4W1Fy4
series <- lapply(split(plotData, plotData$category), function(x) {
    res <- lapply(split(x, rownames(x)), as.list)
    names(res) <- NULL
    return(res)
})

invisible(sapply(series, function(x) {
    h1$series(data=x, type="scatter", name=x[[1]]$category)
}
))

h1$legend(enabled=FALSE)

# Force circle markers and change size
h1$plotOptions(scatter=list(marker=list(symbol='circle', radius=6)))

h1$tooltip(formatter = "#! function() { return this.point.name + ', ' + 
           this.series.name + ', ' + this.x + ', ' + this.y; } !#")

# Enable exporting
h1$exporting(enabled=TRUE)

# Set name
h1$set(dom=xLabel)

# Print chart
print(h1)
#h1$show("inline")

Highcharts/rCharts 文件夹：libraries/widgets/highcharts

此文件夹包含 config.yml：

config.yml

highcharts:
  jshead:
    - js/jquery-1.7.min.js
    - js/highcharts.js
    - js/highcharts-more.js
    - js/exporting.js

布局/文件夹有 chart.html

chart.html

<script type='text/javascript'>
    (function($){
        $(function () {
            var chart = new Highcharts.Chart({{{ chartParams }}});
        });
    })(jQuery);
</script>

Answer 1

我不认为 3D 图表在 rCharts 中可用，因此不存在 z 轴上的错误。

相反，您必须使用包 rthreejs based on Ramnathv's htmlwidget 包，它也适用于 Rmarkdown 和 Shiny。

devtools::install_github("ramnathv/htmlwidgets")
devtools::install_github("bwlewis/rthreejs")

libs <- c("htmlwidgets", "threejs")
lapply(libs, library, character.only=TRUE)

Example 在 htmlwidget galery

Answer 2

现在有另一个 R 的 highcharts 包装器。包括 3d 模块。此处示例：http://jkunst.com/highcharter/highcharts-api.html.

代码

data(citytemp)

hc <- highchart() %>% 
  hc_xAxis(categories = citytemp$month) %>% 
  hc_add_series(name = "Tokyo", data = citytemp$tokyo) %>% 
  hc_add_series(name = "London", data = citytemp$london) %>% 
  hc_add_series(name = "Other city",
                data = (citytemp$tokyo + citytemp$london)/2)  %>% 
  hc_chart(type = "column",
           options3d = list(enabled = TRUE, beta = 15, alpha = 15))

hc
