Is there a plot that goes with this legend?

Can you provide 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 issue The minimal runnable code necessary to reproduce the issue, 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 these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

here is the code from the plot i have generated.

plot(x = mydat2$latL, y = mydat2$latRG, xlab = "Lateral Luminance Colour", ylab = "Lateral Red-Green Colour")

thank you for your time : )

@tiagibbon

mydat2

We don't have access to mydat2, hence why a reproducible example would be good. See the article.

The problem with your legend might be with the position of it though. Try playing around with these x = -0.05, y = 300. They should reflect the x and y limits on your graph.

Have a look at ggplot2 as well. It is probably the most commonly used package for graphs in R.
