Good morning all,

I have been trying to reproduce some figures that I have done about two years ago. Unfortunately my old .do file got wiped out accidentally so I need to figure it out all over again.

In my raw data set I have a variable for C-reactive protein levels in a given population. Looking at the distribution of CRP levels across study sample, data is positively skewed.

Thus I log transformed variable using the command: gen logcrp = log(crp)

When I plot the data on histogram, I get different x-axis to what I got in the past. Is there a possible explanation for this please? It's the same variable, same values...so I really don't understand the reason behind it.

The original histogram is on the right, the new one on the left.

Any help or imput will be greatly appreciated. Thank you
