plot is all black

[badcoder]

I am running a plot and it is all black, my data is just a series of returns and dates -
I have no error messages

Here is my code

returns <- read.csv("/Users/Analytics/HWS/F-F_Research_Data_Factors.CSV")
plot(returns$Date,returns$Mkt.RF,xlab="Date",ylab="Excess Return",col="blue")

There's not enough information to help you. Can you provide the code to generate this plot in form of a reprex?

[badcoder]

yes apologies i thought I had posted it

returns <- read.csv("/Users/Analytics/HWS/F-F_Research_Data_Factors.CSV")
plot(returns$Date,returns$Mkt.RF,xlab="Date",ylab="Excess Return",col="blue")

the data has 4 columns with 1000 entries each

thanks!

Your example is not actually reproducible, since we don't have access to your local files. Please read more carefully this FAQ and rephrase your question as a reproducible example.

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the error The minimal runnable code necessary to reproduce the error, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of this with an example: Minimal Dataset (Sample Data) You need to provide a dataframe that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as example, that you are working with the iris dataframe head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.2 se…
