Hi, I am trying to use Plot-Statistical-Histogram to plot the following histogram and the normal fitting curve. But I do not have the original data and it seems to me that the Histogram in Originlab need the raw data to automatically plot each bin and count. What should I input to plot this graph? Thank you.

The fitting on the binned data is not appropriate here as there are not enough data points (only 4) for the fitting.

U can plot the binned data as column/bar with no gap and do fit.

Thanks, Snow



Thanks for replying. I plot the binned data and fit the number with Gauss in Nonlinear Curve Fit. The resulting curve is not the same as the expected curve. Can you help me with the fitting? Thanks.
