如何在 r 中使用 plotly 更改 x 轴布局

How to change x-axis layout using plotly in r

我正在尝试自定义 x 轴。我目前在 x 轴上有 "Site" 变量。范围是从 15 到 24,每个数字都有站点 a 和 b,即对于 15,有 15a 和 b(依此类推到 24)。当我标记所有条形图时,它看起来很乱,我正在尝试对其进行自定义,例如,数字 15 在下方,但各个条形图标记为 a 和 b。这样,各个条形图将是可识别的,但看起来不会那么拥挤。

到目前为止,这是我的代码:

#Stacked bar chart exp2 
BarChartData2 <- read.csv("Bar chart data exp 2.csv")
Site <- BarChartData2[,4]
Card <- BarChartData2[,2]
Pen <- BarChartData2[,3]
data2 <- data.frame(Site, Card, Pen)
pstacked2 <- plot_ly(data2, x = ~Site, y = ~Card, type = 'bar', name = 'Card', marker = list(color = 'Black')) %>%
  add_trace(y = ~Pen, name = 'Pen', marker = list(color = 'red')) %>%
 layout(yaxis = list(title = 'Number of Bee Visits'), barmode = 'stack',  font = list(family = 'Times New Roman', size =14, color ="black"), xaxis = list(autotick = F, dtick = 2))
pstacked2

任何 help/other 如何做到这一点的想法将不胜感激!

这里有一些东西可以帮助你。你可以玩 shapesannotations 来得到你想要的。

plot_ly(data2, x = ~Site, y = ~Card, type = 'bar', name = 'Card', marker = list(color = 'Black')) %>%
  add_trace(y = ~Pen, name = 'Pen', marker = list(color = 'red')) %>%
  layout(yaxis = list(title = 'Number of Bee Visits'), 
         barmode = 'stack',  
         font = list(family = 'Times New Roman', size =14, color ="black"), 
         xaxis = list(autotick = F, dtick = 2),
         margin = list(
           r = 10, 
           t = 25,

           l = 110
         ),
         shapes = list(
