[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 http://imgur.com/y8sUzSM

[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)) [環境敘述]: R version 3.2.5 Patched (2016-05-05 r70791) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under: OS X 10.12.1 (unknown) locale: [1] zh_TW.UTF-8/zh_TW.UTF-8/zh_TW.UTF-8/C/zh_TW.UTF-8/zh_TW.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] RJDBC_0.2-5 rJava_0.9-8 DBI_0.4-1 corrplot_0.77 [6] RColorBrewer_1.1-2 googlesheets_0.2.0 gridExtra_2.2.1 plotly_4.5.2 [11] sp_1.2-3 ggplot2_2.1.0 DT_0.2 stringr_1.0.0 [16] tidyr_0.4.1 dplyr_0.4.3 loaded via a namespace (and not attached): [1] Rcpp_0.12.6 cellranger_1.0.0 plyr_1.8.4 base64enc_0.1-3 t oo [6] digest_0.6.10 evaluate_0.9 jsonlite_1.1 tibble_1.2 g ta [11] lattice_0.20-33 viridisLite_0.1.3 yaml_2.1.13 parallel_3.2.5 k ni [16] httr_1.1.0 htmlwidgets_0.7 gtools_3.5.0 grid_3.2.5 R 6_ [21] rmarkdown_1.0 foreign_0.8-66 purrr_0.2.1 magrittr_1.5 s ca [26] htmltools_0.3.5 assertthat_0.1 colorspace_1.2-6 stringi_1.1.1 l az [31] munsell_0.4.3 [關鍵字]: plotly , 視覺化 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 140.119.120.6 ※ 文章網址: https://www.ptt.cc/bbs/R_Language/M.1481549977.A.692.html ※ 編輯: open272 (140.119.120.6), 12/12/2016 21:43:48
