Hi Rene, Maybe I misunderstand something, but if I have a plot of a histo on my canvas and via 'right-clicking' switch to a log scale on e.g. the y-axis the popup box prompts me for a number. If I enter 0, the y-axis will stay in linear scale. If I enter 1, I get a standard log-scale in steps of 10. I would expect that if I enter e.g. 3 I would get a log scale in steps of 10**3 etc... However, I don't think currently it works this way. In case I am correct, it seems that this procedure is currently not correctly working. If I am not correct, could you then please tell me what the number means which I have to enter. And furthermore, could a functionality like the above be implemented ? This would solve Florian's problems and also provide a nice facility to make appropriate plots. Cheers, Nick.
