                              質問 # 183
                              You have the following dashboard that contains two visualizations.

                              You want to show only one visualization at time. Users must be able to switch between visualizations.
                              What should you me?

                              正解：C

                              解説：
                              In Tableau, you can manage the visibility of different visualizations on a dashboard using various techniques.
                              Among the options provided, the most straightforward method to allow users to switch between two visualizations is to use show/hide buttons.
                              Here's why each option is or isn't suitable for the requirement:
                              A). A parameter and a calculated field: While it's possible to use a parameter and a calculated field to control which visualization is displayed, it requires creating a calculated field that responds to a parameter and then using that field to filter the view. This method can become complex and is not as user-friendly for simply showing and hiding visualizations.
                              B). Worksheet actions: Worksheet actions in Tableau typically allow users to interact with the data within a visualization, such as filtering data or highlighting related data points when clicking or hovering. They are not designed to control the visibility of entire visualizations on a dashboard.
                              C). Show/hide buttons: Show/hide buttons are a feature specifically designed to manage the visibility of dashboard elements. When you create a show/hide button, it can be configured to display or hide a particular visualization, container, or any other dashboard element when clicked. This provides a very intuitive interface for users to switch between visualizations.
                              D). Dashboard actions: Dashboard actions, like worksheet actions, are used to create interactions between sheets, such as filtering data or navigating to other sheets or URLs based on user interactions. They are not intended for toggling the visibility of visualizations.
                              Therefore, the correct answer is C. Show/hide buttons as they provide a user-friendly way to switch between visualizations on a dashboard without the need for complex calculations or actions that aren't meant for this purpose. The show/hide button feature is specifically designed for toggling visibility and offers a simple and effective solution for the requirement.


                              質問 # 184
                              You have the following dataset in Microsoft Excel.
                              You are using Data interpreter to cleans the dataset. Data interpreter provides the following results.
                              How many rows of data will be ingested into Tableau as values?

                              正解：C

                              解説：
                              Data interpreter is a feature that helps you clean and structure your data in Excel before importing it into Tableau. It detects and removes any headers, footers, subtotals, or other elements that are not part of the actual data. It also splits any merged cells and fills in any missing values. In this case, data interpreter provides the following results:
                              * It removes the first three rows and the last two rows that contain headers and footers.
                              * It splits the merged cells in column A and fills in the missing values with "Fiction" or "Non-Fiction".
                              * It does not remove or change any other rows or cells.
                              Therefore, the number of rows of data that will be ingested into Tableau as values is 17, which is the number of rows left after removing the headers and footers. References: https://help.tableau.com/current/pro/desktop
                              /en-us/importing_cleaning_up_data.htm https://help.tableau.com/current/pro/desktop/en-us
                              /importing_data_interpreter.htm
                              Based on the Data Interpreter's results and the provided Excel dataset screenshot, the number of rows of data that will be ingested into Tableau as values is 17. The Data Interpreter has identified and excluded headers and footers, and the rows with actual data are considered for analysis.
