Function plot appears reversed

Hello, The plotted function Y value is e20 when it should be 13.6e1. So rather than a graph starting linear and going constant it rises exponentially on the Y axis. Eventually this graph will be used to demonstrate the constant region. The initial fit from which this function is taken is correct. Can anyone suggest why this miscommunication occurs?

You made a mistake somewhere. So either there is a bug in your code, or you misread some help, etc. Who knows? Computers do exactly as they are told to do. You told your computer to do something the wrong way, on way or another.

Given the incredibly vague information you have provided, it is very difficult to know more. The crystal ball is so foggy today. I sent away for some Murphy's Magic Crystal Ball Cleaner via mail order though, so if you wait a few days, perhaps it will arrive.

If you want a better response, then show what you have done. Perhaps attaching the model you have fit as a .mat file would be useful. Show the plot you generated that you think seems wrong. Showing your code would be very useful too. Otherwise, you cannot expect much more than vague generalities.

Thank you for the response, perhaps you could try looking into 'the magic pond'; I hear this mail order is unreliable.

On much consideration during today's shower I have decided this plot is quite adequate. It now shows the function Optima or constant is on the X axis as I expected the second derivative. I will calculate this value and, pale with the plotted value.

Drat. I was so hoping the mail order would come through. You are right though, the set of MATLAB tarot cards I ordered from that same source were of very cheap quality. They predict the past well enough, but that is all.
