Logarithmic scale for threshold and noise histograms

Hi all,

I have a request regarding the threshold and noise histograms that are included in the output pdf of the threshold and in-time threshold scans. In addition to the standard plot with the y-axis in linear scale, I think it can be interesting to have also the same histogram with a logarithmic y-axis scale... It could be very useful to have a better visual feeling about tails in the distributions and outliers, or anyway pixels that deviate significantly from the main trend. Would it be possible to implement it for the next release?

Thanks, Ennio
