Create the Chart

Chart Wizard button

Begin by selecting the range of worksheet data you want to include in the chart. Then click the Chart Wizard button. Follow the instructions in the wizard to specify the chart type and options you want. The wizard offers you the option of creating a chart on the worksheet, or creating a separate chart sheet in the workbook. If you create a chart on the worksheet, you can reposition and resize it.

How do you indicate whether rows or columns are the data series?   Specify this in step 2 of the Chart Wizard when you create the chart. Microsoft Excel proposes data series in rows or columns based on the dimensions of the range you selected. Check the sample to see if the setting is right, and try it the other way if necessary. Want to alter a chart?   In a chart placed on a worksheet, simply click the item you want to change. To activate a chart sheet, click its tab at the bottom of the workbook. The Chart menu and toolbar appear.
