To get this option, right-click on Forecast diagram as shown in the following screenshot. You can also get minute details of the forecast model by choosing the option Describe Forecast. Create the first view (a map for each state showing obesity rates at the county level) : o Double click on State. o Tableau automatically recognizes catego rical fields, like State, and numerical measures like Adult obesity rate. o At the dialog box, click OK to connect. Choose the Forecast Length as 2 years and leave the Forecast Model to Automatic as shown in the following screenshot.Ĭlick OK, and you will get the final forecast result as shown in the following screenshot. on top of the Tableau Public icon on your desktop to open. Step 2 − On completing the above step, you will find the option to set various options for forecast. Go to the Analysis tab as shown in the following screenshot and click Forecast under Model category.

To achieve this objective, following are the steps. Using the Sample-superstore, forecast the value of the measure sales for next year. Tableau takes a time dimension and a measure field to create a forecast. The result of a forecast can also become a field in the visualization created. These models capture the evolving trend or seasonality of the data and extrapolate them into the future. In exponential smoothing, recent observations are given relatively more weight than older observations. Tableau uses the model known as exponential smoothing.
There are many mathematical models for forecasting. Forecasting is about predicting the future value of a measure.
