Using Data Visualization Blocks: Charts and Graphs
Transform numbers into visual stories. Learn how to add charts, customize data, and choose the right visualization for your information.
Prerequisites
- Customizing your presentation
- Basic block usage
Using Data Visualization Blocks
Numbers alone don't persuade—visual data does. Charts and graphs make complex information instantly understandable and memorable.
Time: 3 minutes
Level: Intermediate
Prerequisites: You understand blocks and editing
Choosing the Right Chart Type
Each chart type tells a different story.
Bar charts: Compare values across categories. Use for sales by region, feature adoption rates, or survey results.
Line charts: Show trends over time. Perfect for growth metrics, seasonal patterns, or progress tracking.
Pie charts: Display parts of a whole. Use when showing percentages or proportions (max 5-6 slices).
Area charts: Like line charts but emphasize volume. Great for cumulative data or multiple metrics stacked.
Scatter plots: Show relationships between two variables. Use for correlations or distributions.
Result: The chart type should match your data's story—comparison, trend, or composition.
Adding a Chart to Your Slide
Insert data visualizations in seconds.
- Open the Blocks drawer on the right
- Find the Charts & Data category
- Click the chart type you need (Bar, Line, Pie, etc.)
- The chart appears on your slide with sample data
- Click the chart to open the data editor
What you see:
- A formatted chart matching your theme
- Sample data showing how the chart works
- Data editor panel for customization
Tip: Start with sample data to understand the chart structure before adding your own numbers.
Result: A theme-styled chart ready for your data.
Editing Chart Data
Replace sample data with your information.
- Click your chart on the slide
- The data editor opens in the right panel
- Click inside any cell to edit values
- Press
Tabto move to the next cell - Add or remove rows using the + and − buttons
For bar and line charts:
- First column: Category labels (months, products, teams)
- Remaining columns: Numeric values
- Column headers: Legend labels
For pie charts:
- First column: Slice labels
- Second column: Values (percentages or raw numbers)
Tip: Copy data from Excel or Google Sheets and paste directly into the data editor—it works.
Result: Your chart updates in real-time as you edit data.
Customizing Chart Appearance
Make your charts match your message and brand.
To change colors:
- Select your chart
- Find Colors in the chart settings
- Choose from theme colors or custom colors
- Each data series gets a different color
To edit labels:
- Click Labels in chart settings
- Edit the chart title
- Enable or disable axis labels
- Add data value labels to bars or points
To adjust sizing:
- Drag chart corners to resize
- Maintain aspect ratio or stretch to fit
- Position anywhere on your slide
Result: Professional data visualizations that match your presentation style.
Showing Multiple Data Series
Compare multiple metrics in one chart.
Bar charts: Show multiple bars per category (grouped or stacked).
Line charts: Display multiple trend lines with different colors.
Area charts: Stack multiple data series to show cumulative totals.
To add series:
- Open the data editor
- Click + Add Series
- A new column appears
- Name the series and add values
- The chart adds another visual element
Use cases:
- This year vs. last year revenue
- Feature A vs. Feature B adoption
- Multiple product lines or teams
Tip: Limit to 3-4 series maximum. More than that becomes hard to read.
Result: Rich comparisons that tell complex stories simply.
Chart Best Practices
Follow these rules for clear, persuasive data visualization.
Simplify ruthlessly: Remove gridlines, extra labels, and decoration. Show only essential elements.
Start Y-axis at zero: Starting elsewhere distorts perception and misleads audiences.
Use consistent colors: Same color = same metric across all slides. Don't change colors randomly.
Label clearly: Axes and legends should be obvious. Audiences shouldn't guess what numbers mean.
Round numbers: Use "5.2M" instead of "5,234,892". Precision rarely matters in presentations.
Highlight key data: Use accent colors to draw attention to the most important bar, line, or slice.
Result: Charts that communicate instantly without explanation.
Common Data Visualization Mistakes
Avoid these pitfalls when creating charts.
Too much data: Six bars are clear, twenty bars are noise. Aggregate or split across slides.
3D effects: They look fancy but distort perception. Always use flat, 2D charts.
Wrong chart type: Pie charts for trends (no!), line charts for categories (no!). Match type to data.
Tiny text: If axis labels are unreadable, make the chart bigger or use fewer data points.
Rainbow colors: Use a limited color palette (2-4 colors maximum) that matches your theme.
Fix: Choose the right chart type, simplify data, and style consistently.
Animating Charts for Presentations
Reveal data progressively for impact.
- Select your chart
- Click Animation in chart settings
- Choose animation style: Fade In, Slide In, or Grow
- Set animation order if you have multiple charts
When to animate:
- Building to a conclusion (show data points one by one)
- Comparing before/after (show baseline, then result)
- Revealing surprising data (build anticipation)
When not to animate:
- Static presentations (PDF exports)
- Simple charts with obvious data
- Time-constrained presentations
Result: Animated charts focus attention and add drama to your data story.
What You've Learned
- Selecting the right chart type for your data
- Adding and customizing charts on slides
- Editing data directly in the chart editor
- Styling charts to match your theme
- Showing multiple data series effectively
- Following visualization best practices
Next Steps
- Combine with images: Add context to your data in Mastering Slide Layouts
- Create persuasive decks: Apply data skills in Building Sales Presentations That Convert
- Perfect your theme: Style charts consistently in Choosing the Right Theme
Pro tip: Create your charts in Outline rather than importing screenshots. Live charts are editable, match your theme automatically, and export cleanly to PowerPoint.
