Chartsheetobject represents a worksheet that contains only a chart.
Anchors behave slightly differently on Chartsheets than on regular worksheets. When creating an anchor, the row and column properties are ignored. The OffsetX and OffsetY properties specify a percentage value, with 0 corresponding to the left or top edge, and 100 corresponding to the bottom or right edge of the Chartsheet. This allows you to add a shape or picture to an arbitrary position on the Chartsheet.
Similarly, the Width and Height properties on Shapes, Pictures, and Groups specify a percentage of the total width or height of the chartsheet. So a Shape with a width of 25 would occupy 25% of the Chartsheet.
You can have as many Shape, Pictures, and Groups as you wish on the chartsheet. However, you may only have one chart on the chartsheet, which is specified with the Chart property.
Some Worksheet properties are not valid on a Chartsheet.
The following table summarizes the behavior of Worksheet properties on Chartsheets. If you try to access or set a property on a Chartsheet that is not valid, an InvalidOperationException will be thrown. Some properties will behave as AutoProperties, but will have no effect in the saved file. If the property is supported but there are differences in behavior from Worksheets, the differences are described in the Notes column.
