Plotting Confidence Intervals for Time Series

I found this tutorial here that shows how to plot time series and confidence intervals : dygraphs for R (scroll to bottom)

I tried to do this for a different class of models:


# Fit the ARIMA model
fit <- auto.arima(ldeaths)

# Get the predictions with 95% confidence interval
pred <- forecast(fit, h=12, level=0.95)


dygraph(cbind(ldeaths, pred$lower, pred$mean, pred$upper), main = "Deaths from Lung Disease (UK)") %>%
    dySeries("ldeaths", label = "Actual") %>%
    dySeries(c("pred$lower", "pred$mean", "pred$upper"), label = "Predicted", fill = "red")

Have I done this correctly?
