Hi All, I have been trying to plot multiple line plots with different colors on one figure. in my example below I was able to plot cat vs num1 as a dot plot connected with lines but was not able to do that for cat vs num2 and I do not know how to add the third plot cat vs num3. below is my code
df <- data.frame(cat=1:10, num1=rnorm(10), num2=rnorm(10), num3=rnorm(10)) plot(df$num1, type="b", col="red", xlab="categories", ylab="random numbers") points(df$num1, type="p", pch=21, col="red",bg="red") #plot "num1" points(df$num2, type="p", pch=21, col="green") #plot "num2" legend(x="topright", legend=c("num1", "num2"), pch=c(16,16), col=c("red","green")) #add a legend how to make the second plot of type="b" and how to add a third plot cat vs num3?
