Data is a powerful tool to persuade, inform, and inspire your audience. But how do you present data on slides with charts in a way that is clear, compelling, and memorable? In this article, you will learn some slide design principles and tips to help you create effective data slides with charts.
The first step to present data on slides with charts is to choose the right chart type for your message and data. Different chart types have different strengths and weaknesses, and you should match them to your purpose and audience. For example, if you want to show trends over time, a line chart is a good option. If you want to compare proportions or percentages, a pie chart or a stacked bar chart might work better. If you want to show relationships or correlations, a scatter plot or a bubble chart can be useful. You can also use a combination of chart types to highlight different aspects of your data, but avoid using too many or confusing ones.
When presenting data on slides with charts, the second step is to simplify and declutter your charts so that they are easy to read and understand. To do this, you should give a clear and descriptive title and label your axes and data points. Additionally, use consistent and contrasting colors and fonts, while removing gridlines, borders, backgrounds, and other visual noise. Legends should be minimal or not used at all; instead, explain them verbally or in text boxes. Highlight the key data points or trends with markers, annotations, or callouts. Lastly, avoid 3D effects, animations, and other gimmicks that can distort or distract from your data.
When presenting data on slides with charts, it is important to align your charts with your narrative. This means using your charts to support and enhance your story, not replace or contradict it. To do this, use one chart per slide and focus on one main message or takeaway. Utilize transitions and animations to gradually reveal your data and guide your audience's attention. Include captions, headings, or questions to frame your charts and link them to key points. Utilize comparisons, contrasts, or benchmarks to provide context and meaning to your data. And use storytelling techniques such as anecdotes, metaphors, or emotions to connect your data to your audience's interests and values.
The final step to present data on slides with charts is to test and refine your charts for accuracy, reliability, and effectiveness. You should check your data sources, calculations, and assumptions for errors or biases, and use appropriate scales, intervals, and formats. Additionally, you can ask for feedback from colleagues, friends, or experts to incorporate their suggestions or critiques. Practicing your presentation and observing how your audience reacts to your charts can also be beneficial. By making adjustments or improvements based on your observations and feedback, you can present data on slides with charts in a way that is clear, compelling, and memorable. With the right data, you can persuade, inform, and inspire your audience with confidence and credibility.
