这是一个用 Rbokeh 表示的简单条形图示例。

library(rbokeh)

# total yield per variety
figure() %>%
  ly_bar(variety, yield, data = lattice::barley, hover = TRUE) %>%
  theme_axis("x", major_label_orientation = 90)

结果如下图

在此处输入图像描述

问题 1) 我想绘制条形图，在 x 轴上按产量按降序重新排序

我知道在 ggplot 中有一种简单的方法可以使用“重新排序”功能，但不知道如何在 Rbokeh 中做到这一点。

我怎样才能做到这一点？

问题2） 运行上面的代码，我可以看到这个错误信息，这是什么意思，我该如何解决这个问题？

xlim对于第一个问题：您可以通过在*中指定顺序来控制分类轴的顺序。但首先你应该对“品种”进行分组。我做了：

barley_data <- lattice::barley %>% 
  group_by(variety) %>% 
  summarise(yield = sum(yield))

然后，生成图：

figure(xlim = barley_data$variety[order(-barley_data$yield)]) %>%
  ly_bar(variety, yield, data = barley_data, hover = TRUE) %>%
  theme_axis("x", major_label_orientation = 90)

对于第二个问题，或许可以参考这个。
