情節多列使用GGPLOT2

Question

我有一個數據集，如：

head(TI_plot) 
# A tibble: 6 x 6 
    MeanWindSpeed_mean TurbInt_mean NTM_A_Plus_mean NTM_A_mean NTM_B_mean NTM_C_mean 
       <dbl>  <dbl>   <dbl>  <dbl>  <dbl>  <dbl> 
1   0.2920231 3.0270543    Inf  Inf  Inf  Inf 
2   1.1201188 0.4204022  1.1026039 0.9800923 0.8575808 0.7350693 
3   2.0283907 0.2641950  0.6423299 0.5709599 0.4995900 0.4282200 
4   3.0094789 0.2151093  0.4730658 0.4205029 0.3679401 0.3153772 
5   4.0142807 0.1879412  0.3874176 0.3443712 0.3013248 0.2582784 
6   5.0125075 0.1669939  0.3367696 0.2993508 0.2619319 0.2245131 

我應該如何使用ggplot2繪製這些列的3對MeanWindSpeed_mean？ 我想繪製的Rhe列是TurbInt_mean,NTM_A_mean和NTM_B_mean。

Answer 1

選擇和轉換數據使用dplyr和tidyr（從tidyverse）和陰謀使用ggplot2：

library(tidyverse) 
TI_plot %>% 
    select(MeanWindSpeed_mean, TurbInt_mean, NTM_A_mean, NTM_B_mean) %>% 
    gather(key, value, -MeanWindSpeed_mean) %>% 
    filter(!is.infinite(value)) %>% 
    ggplot(aes(MeanWindSpeed_mean, value, color = key)) + 
     geom_point(size = 2) + 
     geom_line(size = 1.4) + 
     labs(x = "Wind Speed, mean", 
      y = "Recorded signal", 
      title = "Change in measurement according to wind speed") + 
     scale_color_brewer(name = "Measurement", palette = "Dark2") + 
     theme_classic()
