Need custom plotting/graphing tool for website

I am looking for someone who can develop an online plotting tool for two predefined equations, with several user-defined variables. The tool will be added to an existing electronics do-it-yourself website.

In summary, website visitors will see a default plot of the two equations and shall be able to adjust six variables via numerical entry (so that the curves change based on user entries). The logarithmic plot shall have a fixed window, and it must be possible to "hold" the curves (such that users can compare curves before and after variable changes).

A rough example of this idea has been tested in Matlab. I simply need it to be accessible online.

Files have been resubmitted (see ""). There was a minor error in the equations, which has been corrected.

Project remains identical.

Also added clarified list of equations, "Equations List, v3.pdf".

Tool must simultaneously show both curves for "Gain (decibels)" equations. This was done in the "Matlab Example Plot" image, but required clarification.

The tool does NOT need to use the "Voltage Gain" form of the equations, unless coder wishes to add the ability to switch between "Gain (decibels)" and "Voltage Gain".

I can do that for you. I will implement in JavaScript and that will keep previous graph line with different color so that he can compare. I am also a mathematician so knows about it very well. Please see PMB for .
