However for this new series it should start shifted over 22 integers on the x-axis. Its initial x-value is 23, but it is still starts above the day 1 value for the initial series. I haven't made a reproducible example since it seems like this could have a simple solution.

Code for series is:

Code:

```
plot(x = x_IS, y = y_IS,
type = "l",
lty = 2,
lwd = 2,
col = "black",
axes = FALSE,
xlab = NA,
ylab = NA)
```
