Using the Forecasting Feature in Power BI

PTR is proud to provide Power BI Consultancy Services to help you and your business get the most from your data but when only a quick answer will do, here is the latest in our series of bite-sized “How to” guides for Power BI, looking at how to use the forecasting feature in Power BI.

The forecasting feature in Power BI uses machine learning algorithms to predict future values based on historical data. This helps businesses to make informed decisions, plan for future trends, and adjust strategies, leading to increased efficiency, profitability, and customer satisfaction.

By leveraging the power of machine learning and incorporating it into forecasting models, businesses can improve the accuracy of their predictions and create custom forecasting models based on their specific needs.

Additionally, Power BI allows users to adjust the forecast by specifying the confidence interval and smoothing parameter, thereby improving the accuracy of the forecast and providing more reliable insights for decision-making.

So the forecasting feature in Power BI really gives businesses a powerful advantage, helping you stay ahead of the competition, adapt to changing market conditions, and make informed decisions - all based on predictive analytics.

Steps to take when using the forecasting feature in Microsoft Power BI 

• Import Data: First, import your data into Power BI.

• Visualize the Data: Create a visual representation of your data, such as a line chart, that includes a time-based axis.

• Enable Forecasting: Select the visual, then expand the Forecast section of the Analytics pane.  The forecast option will only be visible if Power BI recognises the data as date or time. It is important to make sure datatypes are assigned correctly, as using string labels will not work with forecasting.

• Configure the Forecast: Modify the forecast by specifying inputs such as the Forecast length or the Confidence interval. You can also adjust the forecast line's colour, style, and transparency.

• Evaluate and Customize: After the forecast is generated, you can evaluate its results and customize it further based on your specific requirements.

• It's important to note that while using the forecasting feature, the ability to use dynamic reference lines is based on the type of visual being used. For example, the forecasting feature is only available for line chart visuals.
