在 R 中,如何使用 highcharter 包复制 highchart 图表
In R how to replicate highchart chart with highcharter package
问:
我需要在我闪亮的应用程序中复制下面的这张图表。但我正在努力处理 javascript 部分 任何帮助都会很棒:
这是 javascript 代码:如何将其“翻译”为 R?
在 R 中处理 javascript 的任何帮助/指示都会很棒。

这会将该 JS 转换为 R/JS(您需要在 Javascript 中收集时间)。当它运行时,我注意到 RStudio 的查看器窗格中有奇怪的垂直线,但这些线没有出现在我的浏览器中。
对于 JS 中的大多数调用,函数或参数在 R 中是相同的。我在 R 代码中使用了时间函数。(不过,你可以将时间设置为静态值,因为时间不受 R 代码控制。highcharter
lubridate
创建图形后,我曾经添加动画,使其遵循实际时间。htmlwidgets::onRender
如果你在没有 的情况下运行它,这就是你将看到的。(好吧,在渲染它的那一刻,您会在时钟上看到当地时间的时间。htmlwidgets
library(highcharter)
library(lubridate)
highchart() %>%
hc_chart(type = "gauge", plotBackgroundColor = NULL,
plotBackgroundImage = NULL, plotBorderWidth = 0,
plotShadow = F) %>%
hc_pane(
background = list(
backgroundColor = list(
radialGradient = list(cx = .5, cy = -.4, r = 1.9),
stops = list(
list(.5, "rgba(255, 255, 255, .2)"),
list(.5, "rgba(200, 200, 200, .2)"))
))) %>%
hc_tooltip(enabled = FALSE) %>%
hc_yAxis(
labels = list(distance = -20),
min = 0, max = 12, lineWidth = 0, showFirstLabel = F,
minorTickInterval = "auto", minorTickWidth = 1,
minorTickColor = "#666", tickColor = "#666",
minorTickPosition = "inside", minorGridLineWidth = 0,
tickInterval = 1, tickWidth = 2, tickPosition = "inside",
tickLength = 10) %>%
hc_add_series(
data = list(
list(id = "hour", y = hour(now()), dial = list(
radius = "60%", baseWidth = 4, baseLength = "95%", rearLength = 0)),
list(id = "minute", y = minute(now()), dial = list(
baseLength = "95%", rearLength = 0)),
list(id = "second", y = second(now()), dial = list(
radius = "100%", baseWidth = 1, rearLength = "20%"))),
dataLabels = list(enabled = F)) %>%
htmlwidgets::onRender("
function(el, x) {
chart = $('#' + el.id).highcharts()
$.extend($.easing, {
easeOutElastic: function (x, t, b, c, d) {
var s = 1.70158; var p = 0; var a = c;
if (t == 0) return b; if ((t /= d) == 1) return b+c;
if (!p) p = d*.3;
if (a < Math.abs(c)) { a = c; var s = p/4; }
else var s = p/(2 * Math.PI) * Math.asin (c/a);
return a * Math.pow(2, -10 * t) * Math.sin( (t * d - s) * (2 * Math.PI)/p) + c + b;
}
});
function getNow () {
var now = new Date();
return {
hours: now.getHours() + now.getMinutes() / 60,
minutes: now.getMinutes() * 12 / 60 + now.getSeconds() * 12 / 3600,
seconds: now.getSeconds() * 12 / 60
};
};
setInterval(function () {
var hour = chart.get('hour'),
minute = chart.get('minute'),
second = chart.get('second'),
now = getNow(),
/* run animation unless we're wrapping around from 59 to 0 */
animation = now.seconds == 0 ?
false : {easing: 'easeOutElastic'};
hour.update(now.hours, true, animation);
minute.update(now.minutes, true, animation);
second.update(now.seconds, true, animation);
}, 1000);
}")
在这个 JS 中,你会看到一些与原始代码的偏差。我需要定义“图表”。我使用用于将任何 R 对象更改为其 HTML 呈现的相同机制来做到这一点:.由于设置间隔的函数最初是创建图形的一部分,因此它是一个未命名的函数。由于我们在渲染图形后调用,因此我删除了外部 .highcharter
chart = $('#' + el.id).highcharts()
function(chart)
