Study Notes
Power BI Visualizations
- Power BI is a cloud-based data visualization tool for creating real-time graphs and displays from various data sources. It's designed to make data more accessible and understandable to users without coding experience.
- Users can publish these visualizations to cloud services for access on any device.
- Power BI dashboards are built through connecting to and transforming data, then creating visualizations, building the dashboard, and publishing it.
- Designers use various visualization types to present data. These types include bar/column charts, line charts, combo charts, area charts, pie charts, donut charts, scatter plots, bubble charts, and KPIs.
Chart Types
-
Bar/Column Charts: Show numerical values as adjacent shapes (horizontal bars for qualitative data; vertical columns for quantitative).
- Stacked: Combine multiple values within a single bar/column.
- 100% Stacked: Combine percentages.
- Clustered: Displays groups of values adjacent to each other.
- Funnel: Values displayed in descending order resembling a funnel.
- Waterfall: Shows a statistic's sequential changes over time or categories.
-
Line Charts: Display value sequences over time (horizontal axis). Commonly used to track financial performance, etc.
-
Combo Charts: Combine line and column charts for comparing datasets with the same x-axis. For example, comparing Profit Margin to Sales and Manufacturing prices.
-
Area Charts: Similar to line charts, but with the area between the line and the x-axis shaded for visual clarity and showing value overlaps.
-
Pie Charts: Use a circle to illustrate percentages, with each slice representing a part of the whole (100%).
-
Donut Charts: Similar to pie charts, but using a ring format.
-
Scatter Plots (and Bubble Charts): Use both axes for numerical values, plotting data points. Bubble charts add a third data dimension by adjusting point size.
-
**Key Performance Indicators (KPIs):**Charts that track the progress of a single data point towards a specific goal. Includes a current value, goal, and a percentage representing the current trend's distance from the target. The background usually shows the current trend.
