  • How do visual calculations make creating reports easier in Power BI?

    -Visual calculations make creating reports easier by providing templates that allow users to quickly apply common calculations without having to write complex DAX formulas.

  • What is the process of adding a running total to a visual in Power BI using visual calculations?

    -To add a running total to a visual, select the visual, go to the Home tab, click on 'New Calculation', use the 'fx' button to select the 'Running Sum' template, choose the appropriate field from the list, and insert it into the calculation.

  • How can users hide or show items in their visuals after applying visual calculations?

    -Users can hide or show items in their visuals by clicking on the eye icons beside each series in the build pane after applying visual calculations.

  • How do visual calculations respond to drill-up and drill-down functionality?

    -Visual calculations respond to drill-up and drill-down functionality just like regular measures, allowing for dynamic data exploration in reports.

  • What is the process of creating a moving average visual calculation in Power BI?

    -To create a moving average, go to 'New Calculation', select the 'Moving Average' template, choose the field (e.g., sum of sales), set the window size for the number of periods to average, and name the calculation.

  • How can users edit visual calculations in Power BI?

    -Users can edit visual calculations by clicking on the calculation in the visual, selecting 'Edit Calculation', making the necessary changes in the visual calculation pane, and then returning to the report.

  • What is the recommended course for mastering Power BI and DAX as mentioned in the script?

    -The recommended course is the Power BI, Power Pivot, and DAX course bundle, which is designed to build skills step by step with practical examples and real-world projects, including personal support from the course creator.

  • How do visual calculations differ from regular measures in terms of field list visibility?

    -Visual calculations are not added to the field list like regular measures, so they do not appear in the list of fields and cannot be formatted with number formatting as usual.

  • What is a workaround for applying number formatting to visual calculations?

    -The workaround for applying number formatting is to edit the calculation, wrap it in the 'FORMAT' function with the desired format string, and then apply the changes.

  • What limitations are currently associated with visual calculations in Power BI?

    -Current limitations of visual calculations include the inability to apply conditional formatting and the lack of appearance in the field list, which also prevents standard number formatting.

  • How can users ensure they are using the latest version of Power BI Desktop with visual calculations enabled?

    -Users should go to the 'File' tab, select 'Options and settings', then 'Options', and under 'Preview features', ensure 'Visual Calculations' is enabled. A restart of Power BI is required for the changes to take effect.
