This Flash Forum article includes source code and instructions for building an applet that allows the user to enter expressions with up to four parameters and then to vary the parameters in order to fit the curve to user data.

The compressed file contains all templates and code referenced within the article, and the brief Developer's Guide (match_guide.pdf ) gives detailed instructions for some specific customization tasks.

Within this article, there is a short description of each of the templates including active versions to demonstrate the functionality of each. In addition, we outline some of the specific customizations that are addressed within the Developer's Guide.

Note: In this article, we are assuming that your are familiar with the basics of Flash's authoring environment. If not, please download the PDF guide from our earlier article "Flash Tools for Developers: Function Grapher," or visit the MathDL Flash Forum Learning Center at
