Plot multiple rows as columns with ggplotly - r

Question

I have the following data

), row.names = c(NA, -4L), class = c("tbl_df", "tbl", "data.frame"
))
and I would like to plot it as this
I thought of transposing the data starting from the second column and name the new transposed data by the first column in the initial data with the following code:
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()
})
However, when I check the "Plot_1_new_data_T" it seems that the first column is named as c("serie1","serie2",..."serie14") and the rest is named as NA.
Any idea how to proceed because I am new to both R and shiny.

Answer 1

Something like this?
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()
Note that the last two columns were removed from this plot, because they are of such a different scale that including them masks any variation in the other columns. If you want to include all the columns, you could use this instead:
ggplot(xm, aes(as.integer(variable), value, color=series)) +
geom_line() +
...
