I am trying to get a polyfit curve from attached excel data, page 12. Data points read in fine and plot. I am getting a plotting error when I try to graph the polyfit function. Using Mathcad Prime 3.1. My goal is to generate an equation that approximates the data points for use in control scheme. I will need to display the coefficients as well. Thank you in advance for your assistance.

Sorry, look at page 12 for the error location.
Sorry but I see only 11 pages!
And I think you not correct plot two vectors and one function. See please my picture!
Sorry - I go to bet...
