Basic Charts

Key Concepts

• Types of Charts:
  • Column/Bar Chart: Best for comparing data across categories (e.g., sales by product).
  • Pie Chart: Ideal for showing proportions (e.g., market share).
  • Line Chart: Useful for trends over time (e.g., monthly sales).
• Chart Elements:
  • Title: Clearly describe the chart.
  • Axes: Show category (x-axis) and value (y-axis) information.
  • Legend: Explain data series.
  • Data Labels: Display exact values on the chart.
• Chart Insertion:
  • Select the data to visualize, then use the Insert tab to choose a chart type.
  • Example: Select a range and click Insert > Column Chart.
• Customization:
  • Add or modify chart elements using the Chart Tools in the Ribbon.
  • Use styles and colors to match your preferences or corporate theme.

Lesson Steps

Common Errors
