Everything went good so far and now I want to add a distribution curve on top of the histogram (which, by the way, is in counts vs diameter(nm)). If I go on "Plot details" I can add the distribution curve by selecting the appropriate distribution function and that's easily done. I also found on internet that another way of doing so is plotting the counts for each bin class and fitting a function on the resulting scatter plot. However, If I select the same fitting function, the new curve differs a bit from the one computed automatically using the "Plot Details" tab. How come so? There must be a difference in the way the curve is created using the two methods but the one computed by "Plot details" is a bit of a black box to me so I don't know which of the two should I prefer. Thanks in advance for any reply.   Check here to subscribe to this topic.
