Hi,
Have a look at the attached image. This is an aircraft performance chart. When we use these charts, we plot differents parameters (altitude, temperature, etc..) and, with a pencil, follow these curves and determine the value we are seeking for (fuel, time, distance, etc.)
I would like to acheive the same programmatically so I determined the polymnomials from the kown curves. However, there can be an infinite number of curves and when the plot falls between 2, I must find a way to come up with a new equation based on the interpolation of 2 polynomials.
The attached image shows a dotted line down to a reference line, then the user follow the closest curve (red) down to the know Y axis value, then vertically down (orange) to the value we are seeking.
What would you suggest?
