時間Mon Dec 12 21:39:35 2016
[問題類型]:
程式諮詢
[軟體熟悉度]:
入門(寫過其他程式，只是對語法不熟悉)
[問題敘述]:
利用plotly套件畫bar plot時，要調整bar標註時發現找不到準確的Ｘ軸位置對應到相對
應的bar中心，參考下圖

[程式範例]:
library(plotly)
Animals <- c("giraffes", "orangutans", "monkeys")
SF_Zoo <- c(20, 14, 23)
LA_Zoo <- c(12, 18, 29)
data <- data.frame(Animals, SF_Zoo, LA_Zoo)
y <- c(20,12,14,18,23,29)
p <- plot_ly(data, x = Animals, y = SF_Zoo, type = 'bar', name = 'SF Zoo') %>%
add_trace(y = LA_Zoo, name = 'LA Zoo') %>%
layout(yaxis = list(title = 'Count'), barmode = 'group',
annotations = list( x =data$Animals,y = y, text = y,
xanchor = 'center', yanchor = 'bottom',
showarrow = FALSE))

1F：→ clansoda: 痾，我有點看不懂敘述，我看你的X軸的值蠻正的阿 12/12 21:46
2F：→ clansoda: 你是要說你的那幾個數字嗎? 12/12 21:47
3F：→ clansoda: 我不清楚plotly的寫法所以我提供一下ggplot的寫法 12/12 21:48
4F：→ clansoda: + geom_text(label = 你要放上去的值, h_just = 用來調 12/12 21:49
5F：→ clansoda: 整的argument，你寫完ggplot以後 最後用ggplotly可以得 12/12 21:50
6F：→ clansoda: 到跟plotly一樣的結果，僅供參考，plotly的需要其他人 12/12 21:50
7F：→ clansoda: 來提供 12/12 21:50
