[R-sig-Geo] Line graph with over 70 lines plotted against time-Resolved

[Jailos Lubinda]

Dear all,

  My issue has been resolved, thanks to Byman, a R-sig-Geo member for 
the help. Just to refresh my question,/**//*I needed to plot a line 
graph of one variable collected over 72 sites(areas) by time (date) 
which meant 72 lines on the same graph*/.
  Here is the solution/code below in case others might have similar issue.

/ # Plot several line graphs//
// library(ggplot2)//
// library(reshape2)//
//
// #changes this line below accordingly//
// dat <- read.table(file.path(""), header = TRUE, sep = ",")//
//
// #Melt the data for easy plotting//
// data <- melt(dat, id = c("DISTRICTS_", "area_name", "Year","Quarter", 
"Date"))//
//
// # format the date column//
// data$Date <- as.Date(data$Date, format = "%d/%m/%Y")//
// #Subset and select the target variable//
// g <- ggplot()//
// g <- g + geom_line(data = data %% filter(variable == 
"Mean.Max.Temp"), aes(x = Date, y = value, group = area_name)) #, colour 
= area_name))//
