I create printable calculators with 3 parameters or more.

To that extent, I need to know the equation behind your application, it can be a scientific law or some empirical formula. I can also retrieve data from a contour plot if you have one.

For each parameter, a range of values has to be given, it can be discrete or continuous. Also, plase specify the dimensions and colours you want for the plot, as well as the title, its position, and so on.

Compound or grid graphs, data digitizing and other non-linear charts might be achievable, but often require a lot of thinking. For some cases, a totally accurate chart cannot exist, but I can try and find a good approximation with less than a 1 percent error overall.
