Hi, your data only has discrete values 1,2,3 … 10. Only the histogram bins which range e.g. from [2.333, 3) (2.3333 <= x < 3) are empty. This is correct as there are really no cases which have values in that range.
The histogram x-axis labeling is now a continuous range. For your specific problem you probably would like to have exactly 10 bins, however the number of bins is selected just based on the data via sturges rule (see https://en.wikipedia.org/?title=Histogram) and adapted slightly to fit to the x-axis tick scaling. You should see the probably desired behaviour when you do a bar chart. Could you maybe try a bar chart?
