Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. To exactly fill the visible range of a worksheet with a graphic object, such as a chart, you must know the exact Top, Left, Height and Width coordinates in points. The ActiveWindow.VisibleRange property returns the range including the partially visible column to the right and the partially visible row at the bottom. You can use the Top and Left property

of that range to get the top and left point coordinates, to get the width property of all columns except the rightmost one, and to get the height property of all rows except the bottom one.

Note, however, that there is no direct way of getting the width of the visible portion of the rightmost column or the height of the visible portion of the bottom row. The only way to get that information is to incrementally make the last column and bottom row wider or narrower until the ActiveWindow.VisibleRange property returns one fewer or more columns and rows.

The Width property of columns is read-only. Therefore, you can only widen a column with the ColumnWidth property, which is measured based on the Normal font rather than in points (the Normal may vary from computer to computer).

Furthermore, the ColumnWidth property will only widen or narrow a column by a certain minimum incremental amount, otherwise the column does not widen. So, it is first necessary to experiment with a column to find the smallest amount that it can be widened. Then, incrementally widen or narrow

it until the VisibleRange property returns one fewer or more columns. After you have determined this measurement, note the new column width and return

the column to its original width.

Row size is easier to determine, because the rowheight property is measured in points; however, rows have a minimum incremental amount by which you can make them shorter, which can vary depending on the type of computer you have.
