2. Choose high-quality pictures: Using high-resolution pictures can improve the readability of the chart. If possible, it is best to use vector diagrams, because they can be kept clear in any size of printing or display.
3. Use clear titles and labels: titles and labels should be concise and clearly explain the contents of the chart. This can help readers quickly understand the meaning of the chart.
4. Use high-contrast colors: Using high-contrast colors can make the chart easier to read and understand. Avoid using too complicated or fancy colors, which may distract the audience.
5. Add notes and explanations: For complex charts, adding notes and explanations is very helpful. This can help readers understand the details and meanings of the chart.
6. Consistency: Make sure that all charts and images are consistent in style, color and font. This can make the report look more professional and make it easier for readers to track information.
7. Check spelling and grammar mistakes: Any spelling or grammar mistakes may affect readers' understanding of the chart. Therefore, it is very important to carefully check and correct these mistakes.
8. Use proper layout: Ensuring that the layout of charts and images is reasonable can help readers better understand and remember information. For example, using grid lines can help readers better understand the distribution of data.
