property GridWidth: Integer;

Type Library
TeeChartx

Description
Read GridWidth to determine the size of the grid. If GridWidth is less than the value of ClientWidth, all of the columns of the grid appear in the control with an empty region to the right of the grid. If the underlying grid is too wide to appear in the control, GridWidth is the same as ClientWidth, and the user must scroll to see the entire contents of the grid.
