- Select Your Data: Click and drag your cursor to select the data you want to include in your chart.
- Insert Chart: Go to the 'Insert' tab, and in the 'Charts' group, click on the type of chart you want to create. A preview will appear, allowing you to choose the best one.

Customizing Your Chart
Once your chart is created, customization is key to making it not only informative but also engaging:
Chart Elements
- Title: Add or edit the chart title to clearly indicate what the chart represents.
- Axes: Modify axis titles, labels, and scales. For charts with two axes, ensure both are labeled.
- Legend: Include a legend to denote what each color or symbol means on your chart.
- Data Labels: Add data labels to show specific values directly on the chart for quick reading.
Style and Layout
You can also adjust the chart's overall style:
- Chart Style: Select from predefined styles or manually change colors, fonts, and other style elements.
- Layout: Experiment with different layouts for your chart elements to improve readability.
| Option | Description |
|---|---|
| Change Chart Type | Switch between chart types or combine charts (e.g., bar and line on the same chart). |
| Select Data | Re-select or adjust the data source if changes are needed. |
| Format | Change fill, borders, and effects for individual chart elements. |
ЁЯМЯ Note: To align your chart with your brand or presentation theme, consider customizing colors and fonts to match.
Advanced Charting Techniques
For those looking to delve deeper, Excel offers several advanced charting options:
Secondary Axes
- Use secondary axes to plot different data sets with different scales on the same chart.
Combination Charts
- Create combination charts where one series is plotted as columns and another as lines to compare different types of data.
Data Analysis Tools
- Use features like Trendlines, Moving Averages, or Error Bars to enhance the analytical aspect of your charts.
ЁЯУК Note: Advanced charting can significantly improve the depth of your data analysis but requires a good understanding of your data and the story you want to tell.
Ensuring Accessibility
Charts should be accessible to everyone, including those with visual impairments:
- Use of Color: Choose color schemes that are colorblind friendly.
- Alternative Text: Add descriptive alternative text for charts to help screen readers describe them to users with visual impairments.
- High Contrast: Ensure there is enough contrast between chart elements and the background.
Creating charts in Excel is not just about displaying data; it's about storytelling with numbers.
