使用 ggplotly 将多行绘制为列

Question

我有以下数据

    dput(head(new_data))
structure(list(series = c("serie1", "serie2", "serie3", 
"serie4"), Chr1_Coverage = c(0.99593043561, 0.995148711122, 
0.996666194154, 1.00012127128), Chr2_Coverage = c(0.998909597935,

1.00161108919, 0.997719609642, 0.999887319775), Chr4_Coverage = c(1.00238874787,

2.50609172398e-07, 8.30448295172e-08, 1.23741398572e-08)), .Names = c("series", 
"Chr1_Coverage", "Chr2_Coverage", "Chr3_Coverage", "Chr4_Coverage", 
"Chr5_Coverage", "Chr6_Coverage", "Chr7_Coverage", "Chr8_Coverage", 
"Chr9_Coverage", "Chr10_Coverage", "Chr11_Coverage", "Chr12_Coverage",

"Chr17_Coverage", "Chr18_Coverage", "Chr19_Coverage", "Chr20_Coverage", 
"Chr21_Coverage", "Chr22_Coverage", "ChrX_Coverage", "ChrY_Coverage"
), row.names = c(NA, -4L), class = c("tbl_df", "tbl", "data.frame"
))

我想把它画成这样

我想从第二列开始转置数据，并用以下代码将初始数据中第一列的新转置数据命名为：

output$Plot_1 <- renderPlotly({
Plot_1_new_data[,2:24] <- lapply(Plot_1_new_data[,2:24], as.numeric)
# first remember the names
n <- as.data.frame(Plot_1_new_data[0:nrow(Plot_1_new_data),1])   
# transpose all but the first column (name)
Plot_1_new_data_T <- as.data.frame(t(Plot_1_new_data[,-1]))
colnames(Plot_1_new_data_T) <- n
#plot data
library(reshape)
melt_Transposed_Plot_1_new_data <- melt(Plot_1_new_data_T,id="series")
  ggplotly(melt_Transposed_Plot_1_new_data,aes(x=series,y=value,colour=variable,group=variable)) + geom_line()
})

但是，当我检查 "Plot_1_new_data_T" 时，第一列似乎命名为 c("serie1","serie2",..."serie14") 并且其余的命名为 NA。

知道如何进行，因为我对 R 和 shiny 都是新手。

Answer 1

是这样的吗？

xm = melt(x)
ggplot(xm[xm$variable != 'ChrY_Coverage' & xm$variable != 'ChrX_Coverage', ], 
       aes(as.integer(variable), value, color=series)) +
  geom_line() +
  scale_x_continuous(breaks = as.integer(xm$variable), 
                     labels = as.character(xm$variable)) +
  theme(axis.text.x = element_text( angle=45, hjust = 1))
ggplotly()

请注意，最后两列已从此图中删除，因为它们的比例如此不同，包括它们会掩盖其他列中的任何变化。如果你想包括所有的列，你可以改用这个：

ggplot(xm, aes(as.integer(variable), value, color=series)) +
   geom_line() +
   ...
