i can not succed to do a simple thing a fit of some values x, y
2.have the error bars
3.plot tougether the fit with the corresponding error bars
i am getting the plot where the error bars are connected by a line so i get two lines with error bars (the line from the fit and the line from the error line)
hold on
hE_1=errorbar(X, Y, err_1);
i am getting something like this:
also any easy way to add the correct legend? as i would like to note only the error bars and the fitted curve with the same color and name it in the legend (in total there are 9 polynoms and the 9 corresponding error bars..)
