Hello all,
I have created a wonderful set of histograms, but I am unable to plot a so called "line of best fit" over the bars. I have read about histfit, but I am not in need of a normal distribution line, I just need a line that will lie accross the tops of the bars on my histogram and I don't know how.

Kind regards,
Terry

You can use polyfit to fit a polynomial of whatever order you specify. If the data indicate to you that a straight line is appropriate, then use order=1.
