Economic cycles plot

[miharbi]

Hi, dears
I want to plot the curve of economic cycles as shown below. I'm looking for an R or Python code that does this.

There are probably a half-dozen or more ways to do this. Can you supply us with whatever code you have and some sample data?

Have a look at

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.…

for some suggestions.

Thank you @jrkrideau for your reply.
In fact, there is no data. It's just an educational illustration.
I only need an economic cycle with its stages. Perhaps a sinusoidal function is sufficient for this.

myfunc <- function(x) sin(x)*100+5*x

(df <- data.frame(x=150:300/10,
                 y=myfunc(150:300/10))) 

min2 <- optimise(myfunc,c(20,25))


ggplot(df) +
  aes(x=x,
      y=y) +
  geom_point() +
  annotate("segment", 
           x = min2$minimum - 2,
           xend = min2$minimum,
           y = min2$objective-1,
           yend = min2$objective, 
           colour = "red",
           size=1, 
           arrow=arrow())    +
    geom_text(data=data.frame(x=min2$minimum - 2.5,
                              y=min2$objective - 5),
               label = "minimum")

Thanks @nirgrahamuk
This is enough for me
