ChartObject Object [Excel 2003 VBA Language Reference]
Represents an embedded chart on a worksheet. The ChartObject object acts as a container for a Chart object. Properties and methods for the ChartObject object control the appearance and size of the embedded chart on the worksheet. The ChartObject object is a member of the ChartObjects collection. The ChartObjects collection contains all the embedded charts on a single sheet.
Using the ChartObject Object
Use ChartObjects(index), where index is the embedded chart index number or name, to return a single ChartObject object. The following example sets the pattern for the chart area in embedded chart one on the worksheet named "Sheet1."
Worksheets("Sheet1").ChartObjects(1).Chart. _ ChartArea.Interior.Pattern = xlLightDown
The embedded chart name is shown in the Name box when the embedded chart is selected. Use the Name property to set or return the name of the ChartObject object. The following example puts rounded corners on the embedded chart named "Chart 1" on the worksheet named "Sheet1."
Worksheets("sheet1").ChartObjects("chart 1").RoundedCorners = True
