How to add additional months to my time series and predict them with exponential smoothing ?

I have this univariate time series for one product.  So for each month I have a single sales value. I added an exponential smoothing operator to it and now I want to predict the next month based on the smoothing curve.
How can I add additional periods to my time series so I can see the prediction in my visualization ?

    Hi,
    you need to add a forecasting method in between. The options are ARIMA, Holt-Winters, Default Forecast and Seasonal Functional forecast (or so).
