What occurs after clicking a single data point in one of the multiple visuals under a report in Power BI?

What happens after clicking a single data point in Power BI depends on several factors, including:

1. Visual type:

• Interactive visuals: For visuals like bar charts, pie charts, or maps, clicking a data point typically highlights it and potentially brings up additional information like hover cards or pop-up details showcasing specific values or related data points.

• Non-interactive visuals: Some visuals like heatmaps or waterfall charts might not inherently react to single clicks but could offer contextual information through tooltips or context menus.

2. Report configuration:

• Cross-filtering: By default, clicking a data point in one visual often applies a filter to other visuals on the report, highlighting data points related to the selected one. This cross-filtering allows you to see the impact of the chosen data point across different aspects of your analysis.

• Drill-down: Some reports are configured to enable drill-down functionality, where clicking a data point takes you to another report page or visualization focusing specifically on that point's related data.

• Custom actions: Reports can be designed with custom actions triggered by clicking data points. These actions could open external web pages, trigger data refresh, or execute specific functions within the report.

3. License and version:

• Power BI Desktop: Clicking data points is generally available in any Power BI Desktop report, regardless of license.

• Power BI Service: Features like cross-filtering and drill-down might require specific Power BI Service licenses like Pro or Premium.

Overall, clicking a data point in Power BI usually serves as an interactive engagement point, providing deeper insights, filtering related data, or triggering specific actions based on your report configuration and license.

Here are some additional points to remember:

• You can often control the behavior of clicking data points in Power BI Desktop by adjusting visual settings or report configuration options.

• Hovering over data points usually reveals tooltips displaying additional information without applying filters or triggering actions.

• Right-clicking data points might offer context menus with further options depending on the specific visual and report configuration.

What visual would you need to use to show solitary esteem in Power BI ? Power BI interview questions and answers 022

 What visual would you need to use to show solitary esteem in Power BI ? 

Unfortunately, the term "solitary esteem" lacks context and clarity, making it impossible to recommend a specific visual in Power BI.

To offer the best recommendation, I need more information about what you're trying to represent with "solitary esteem." Here are some questions that could help:

• What data are you trying to display? (Numbers, percentages, text?)

• What does "solitary" mean in this context? (Uniqueness, independence, self-reliance?)

• What aspect of "esteem" are you trying to show? (Confidence, pride, achievement?)

• What is the purpose of your visual? (Inform, inspire, compare, track?)

Once you provide more information about the data and the meaning you want to convey, I can suggest appropriate visuals in Power BI to effectively showcase "solitary esteem."

For example, if you're using "solitary esteem" to describe high individual performance, you might use a bar chart with individual names and their corresponding performance scores, highlighting the top performers who stand out from the group. Conversely, if you're showing the evolution of someone's confidence over time, you might use a line chart with a single data point for each measurement, emphasizing the individual's personal growth.

Remember, the most effective visuals are those that are clear, concise, and accurately represent the data and its meaning. The more information you provide about "solitary esteem," the better I can help you choose the perfect visual for your Power BI report.

I look forward to hearing from you and helping you visualize your data in the best way possible!

What's the difference between a report and a dashboard in Power BI ?

While both reports and dashboards play a crucial role in data visualization and analysis within Power BI, they serve distinct purposes and have key differences:

Reports:

• Focus: Reports are designed for detailed analysis and exploration of specific data sets. They typically present information through a series of pages, each containing visuals, tables, and filters that allow users to delve deep into different aspects of the data.

• Structure: Reports offer a flexible and customizable structure with multiple pages, allowing you to organize data and insights in a way that tells a specific story or answers a particular question. You can control the flow of information and guide users through your analysis step-by-step.

• Interactivity: Reports provide a high degree of interactivity through filters, slicers, and drill-down capabilities. Users can actively manipulate the data, adjust visualizations, and discover hidden patterns or trends.

• Use case: Reports are ideal for in-depth data analysis, investigative tasks, and sharing specific findings with a focused audience. They're perfect for scenarios where users need to explore details, perform comparative analysis, and uncover complex relationships within the data.

Dashboards:

• Focus: Dashboards provide a high-level overview of key metrics and performance indicators. They typically condense information from multiple data sources onto a single, visually appealing canvas.

• Structure: Dashboards offer a concise and compact layout with a limited number of visuals arranged to present an immediate snapshot of the current state of your data. They prioritize easy access to critical information and quick understanding of trends or deviations.

• Interactivity: While some dashboards offer limited interactivity through filters and navigation options, their primary focus is on immediate consumption and visualization of important metrics.
