Hi,

I am trying to plot a graph between Power and speed. Unfortunately, I have data for for only high speed but I do know that the relationship between power and speed of a ship is a cubic curve. So, I decided to use the curve fitting tool app in MATLAB to predict power at lower speeds. However, I am having a hard time exporting the plot exactly as it is from curve fiiting tool to MATLAB. I am not able to get the data for lower speeds. Please find attached the plots in MATLAB and Curve Fit. Tool.

How can I export the plot as it is to MATLAB so that I have power for lower speeds?

Thanks for the answer Matt. I used this option earlier but I also want to change the name of the both the axes which I can't do with the above option.

I want to get the same plot from the code generate from the app in MATLAB so that I can name the axes.

x axis - propeller speed

Y axis - Delivered power

Both axes names have a space in them.
