Change From plot to ggplot

Question

I have a group of plots currently created in Base R using the code below

plot(PWR_Sports_Racing$`Running P&L`, type="l",col=4, xlab="Bets",ylab="Profit", main = "Racing YTD P&L")
par(new=T)
plot(PWR_Sports_Racing$`BFSP Running P&L`,type = "l",col=2, xlab = "",ylab = "",axes = F)
legend("topright",legend = c("P&L","BFSP P&L"),lty=c(1,1),col=c(4,2))

I would like to convert these to plots created with ggplot2 however when I try to get them to work the output looks worse.

This is where I have got

 ggplot(data = PWR_Sports_Racing) +
  geom_line(mapping = aes(,y=PWR_Sports_Racing$`Running P&L`))+
  ylab("Profit") +
  xlab("Date")

I presume it is something to do with multiple results on each day

Might help if I show some data,

Base Graphics R

Here is some of the data for you to get an idea

PWR_Sports_Racing <- structure(list(dmydate = c(43836, 43837, 43837, 43838, 43838,

Can you provide example data? It's easier to help you if the code/output is 100% reproducible and we don't have to guess at the data you're running this code with. — Tyler Burleigh

I have popped some data in a dropbox link and added an image on the original post. I suppose what I am asking is can this be replicated in ggplot2 — PaulPerton1

Please make your data example reproducible by following guidelines of this link: stackoverflow.com/questions/5963269/…. Right now, your data are avalaible only if we have a dropbox account. It will be preferrable to copy/paste the output of dput(PWR_Sports_Racing) in your question. — dc37

In addition, it's not clear in your question and in your code what is the x axis or the y axis on your plot. What is "Bets" ? Can you clarify it ? — dc37

@PaulPerton1: you will have to convert your data from wide to long format to make ggplot happly. See these examples: stackoverflow.com/a/52789737/786542 & stackoverflow.com/a/51752828/786542 — Tung

Here is a possible solution

# Data set in long format
nr <- nrow(PWR_Sports_Racing)
df <- data.frame(y=c(PWR_Sports_Racing$"Running.P&L",  
                     PWR_Sports_Racing$"BFSP.Running.P&L"),
                 type=rep(c("P&L","BFSP P&L"), each=nr),
                 x=rep(1:nr, 2))

ggplot(data=df, aes(x=x, y=y, color=type)) +
 geom_line(size=1)+
 ylab("Profit") + xlab("Date") + 
 theme_bw() %+replace% theme(legend.position=c(0,1),
                             legend.justification=c("left","top"),
                             legend.background=element_rect(fill=NA,color=NA)) +
 guides(color=guide_legend(title=""))
