The data are usually analyzed and processed by figure in the application of project. Because it is simpler, clearer and easier to show the change of data and find out its regulation. But not having enough control points that have been given, we can't accurately show the regulation of data change with the BEZIER curve. To resolve it, authors describe a new method in this article that is , according to the change trend of control points that have been given ,to insert the new control points by calculation.
