Hello,
I am trying to use the cftool and I got the residual plot fromt it, which is r=y-y^. Is there anyway to make it show a percent residual on the plot? (ie. how many percent the data is off from the fit curve)
Thanks!

You could save your fitting values to workspace, using cftool choose analysis and there select the option evaluate fit at Xi (in your case Xi is your x) . Now if you save those results you 'll have a structure containing xi and yfit. You can calculate percent residuals r(%)=100*(yi-yifit)./yi. Just be careful in case your original data aren't sorted by x value to sort them because the output results of fitting analysis are sorted to xi.
