• Category: A category field appears in the category, or X, axis of all but pie charts. For pie charts, a category field is used for the slices. For example, to show a chart of sales by product by year, use the product name as the category field.

• Values: A values field is the numeric value for each category item in the chart. For pie charts, this is used to determine the size of a slice. For all other charts, it's used for the values, or Y, axis. For example, to show a chart of sales by product by year, use the sale amount as the values field.

• Series: A series field is used to create multiple charts. For example, to show a chart of sales by product by year, use the sale date as the series field and display the year rather than individual dates using the Properties dialog. Not all charts have a series field.
  

To specify where a field goes, drag its name from the list on the left to the appropriate place at the right. For example, to use the Amount field as the values field, click it in the list, hold down the mouse button, and move the mouse until it's over the box below the word "Values," then let go of the mouse.

To remove a field from a place on the report, drag it from the appropriate box back to the list at the left or select it and press the Delete key.

To change how a field appears in the report, select it and click the Properties button. This displays the Properties dialog. You can also display this dialog by double-clicking the field or selecting the field and pressing Enter.

Step 3 shows a sample of what the chart looks like based on the fields you've selected and their properties. However, it does not show actual data from your database until you click the Preview button.
