2. What is a chart? A display of data in graphic form
Easier to read and understand the data from the worksheet
Examples on what a chart can be used for:
Visually analyse data to show comparisons
Visually analyse data to show trends
Visually analyse data to show proportions
Charts are best understood when they are approximately 1/3rd of a page in size

3. Column Chart… Used to show comparisons among items
Or used to show data changes over time

4. Bar chart …
Used to show comparisons among individual items

5. Pie chart …
Used to show proportional size of items that make up a data series

6. Line chart …
Used to show trends in data at equal intervals

7. Parts of a chart …
Plot area is the most important part – this should be enlarged so that the reader gets a better understanding of the charted data

8. Editing a chart …
Use the Chart Tools tab

10. Let’s hope that helped! But, if it didn’t make much sense – I can go through this again!

11. Why would I use a chart?
In business, your workbooks will be generally a lot more complex and a lot larger than the little exercises you are working with and the data will be more difficult to analyse

12. Why else?
Complex data is much easier to read and understand when in graphic format – easy to change display for better understanding
