Thanks for the answer. but ... wouldn't this give me an histogram with a fixed number of bins ? that will have their widths increased as it is filled?
In principle i was asking about something that will scale the axis range (and number of bins) without modifying the bin width. I ask about this because i would like to have a histogram on which i only declare the bin width and that afterwards grow (axis and number of bins) as i fill it.
Thank you,
Best regards,
Adrian
