Simple Histogram using Mathematica - need help please

  1. Aug 30, 2009 #1
    Hi. I am new to using Mathematica v7 and would like to know how to generate a very simple histogram.

    The data is:

    data = {1.5, 2, 0, 0.5, 1, 2, 1.5, 3, 0, 0.5, 1, 2, 2, 3, 3.5, 0, 1, 4, 2, 0.5, 1, 0, 2, 1.5, 0, 1.5}

    I can generate the histogram using Histogram[data] but how do I set the histogram to generate columns that represent 0, 0.5, 1, 1.5, ... etc with the columns labeled with those values centred underneath each column? Is it possible also to have the x-axis label centred underneath the chart?

    Thank you to anyone who can help me out.

    You can try something like
    Code (Text):
    Histogram[data, HistogramCategories -> Range[Min[data], Max[data], 1/2]]
    There doesn't seem to be an option to adapt the scale though (I found somewhere the option Ticks -> IntervalCenters, although it gives me errors).

    Thank you. HistogramCategories and IntervalCenters appears to be in a previous version of Mathematica and not in version 7. If anyone knows what they have been changed to in version 7, I'd appreciate your help!
