title: Remove grey background confidence interval from forecasting plot
body: <p>I created the forecasting plot with the point forecast and confidence interval. However, i only want the point forecast(blue line) without the confidence interval(the grey background). How do i do that? Below is my current code and the screenshot of my plot.</p>
  
  <pre><code>  plot(snv.data$mean,main="Forecast for monthly Turnover in Food   
    Retailing",xlab="Years",ylab="$ million",+ geom_smooth(se=FALSE))
  </code></pre>
