Hi all,

When I add the distribution curve to my lognormal distributed data and scale it to its maximum, the fit seems shifted.
What can I do about it?

If you'd like to plot the lognormal fitted curve with log-scale x axis, please transform the original data to ln(x) first, and run a normal distributed fit on the transformed data. Otherwise the curve will shift to left by the amount of sigma^2.
