HighcharteR 多个工具提示用 hideDelay 打开

Question

基本上我试图让工具提示停留几秒钟而不是在悬停在另一个区域时关闭，即留下旧的打开工具提示的踪迹 like in this example

测试数据：

require(dplyr)
require(highcharter)

mapdata <- get_data_from_map(download_map_data("countries/us/us-all"))
set.seed(1234)

data_fake <- mapdata %>% 
  select(code = `hc-a2`) %>% 
  mutate(value = 1e5 * abs(rt(nrow(.), df = 10)))

hcmap("countries/us/us-all", data = data_fake, value = "value",
      joinBy = c("hc-a2", "code"), name = "Fake data",
      dataLabels = list(enabled = TRUE, format = "{point.name}"),
      borderColor = "#FAFAFA", borderWidth = 0.1,
      tooltip = list(valueDecimals = 2, valuePrefix = "$", valueSuffix = "USD", 
hideDelay = 3, followPointer = F))

我找到了 hideDelay 的选项，但是有没有一个选项可以让工具提示在悬停在另一个区域时保持活动状态（不关闭）？是否有相应的选项，或者是否存在自定义工具提示功能？

或者，带有单击时工具提示的解决方案也会有所帮助，它有一个选项指定旧工具提示不会在再次单击时关闭。

正如@ewolden 所建议的，您可以包装 Highcharts.Tooltip.prototype.updatePosition 函数。为了使其在 R 中工作，您可以将此函数包装在 chart.load 事件中，如本例所示：

require(dplyr)
require(highcharter)

mapdata <- get_data_from_map(download_map_data("countries/us/us-all"))
set.seed(1234)

data_fake <- mapdata %>% 
  select(code = `hc-a2`) %>% 
  mutate(value = 1e5 * abs(rt(nrow(.), df = 10)))

hcmap("countries/us/us-all", data = data_fake, value = "value",
      joinBy = c("hc-a2", "code"), name = "Fake data",
      tooltip = list(followPointer = F), chart = list(
        events = list(
          load = JS("Highcharts.Tooltip.prototype.updatePosition = function(point) {
                var chart = this.chart,
                label = this.getLabel(),
                pos = (this.options.positioner || this.getPosition).call(
                this,
                label.width,
                label.height,
                point
                ),
                anchorX = point.plotX + chart.plotLeft,
                anchorY = point.plotY + chart.plotTop,
                pad,
                cloneToolTip;



                // Set the renderer size dynamically to prevent document size to change
                if (this.outside) {
                pad = (this.options.borderWidth || 0) + 2 * this.distance;
                this.renderer.setSize(
                label.width + pad,
                label.height + pad,
                false
                );
                anchorX += chart.pointer.chartPosition.left - pos.x;
                anchorY += chart.pointer.chartPosition.top - pos.y;
                }

                // do the move
                this.move(
                Math.round(pos.x),
                Math.round(pos.y || 0), // can be undefined (#3977)
                anchorX,
                anchorY
                );
                cloneToolTip = chart.tooltip.label.element.cloneNode(true);
                cloneToolTip = chart.container.firstChild.appendChild(cloneToolTip);
                setTimeout(function() {
                cloneToolTip.remove();
                }, 500)
                }")
                )
              ))
