Can't plot my time series data and training data on the same graph, with different colours?

Im trying to plot both the original data and my training data on the same graph with this code:

timeseries <- ts(df$new_cases_per_million, start=c(2021,2), end=c(2022,3), frequency=52)
ts_train <- window(timeseries,start=c(2021,2),end=c(2022,3))
ts_test  <- window(timeseries,start=c(2022,3))

autoplot(ts_train3,xlab="Year",series="ts_train3") + 
  autolayer(ts_test3,series = "Test set3") +
  ggtitle("timeseries plot")

However when I execute this code, the graph only plots the original data, and not my trained data: enter image description here

I also get this error with my plot:

geom_path: Each group consists of only one observation. Do you need to adjust the group aesthetic?

I want it to look something like this: plot with original data and training data

How could you get a red line when the test data is just a single and the last observation of train data? – Mohanasundaram May 15 '22 at 12:30
yeah, I just realised by looking at my training data set. Thanks Mohanasundaram. – Tuey May 15 '22 at 12:34
How can i change it so that, im testing more than 1 observation? My time series is only from 2021/2 to 2022/3. – Tuey May 15 '22 at 12:39
Maybe you could change `end=c(2021,52)` in `ts_train` and `start=c(2022,1)` in `ts_test`. – Mohanasundaram May 15 '22 at 12:56
Yeah, i tried that but it didn't work, its the same graph but with the red line starting at 2022. – Tuey May 15 '22 at 13:24
You have to decide on the ranges for train data and test data and specify the start and end periods accordingly. – Mohanasundaram May 15 '22 at 13:33
