To generate a histogram, the range of data values for each bar must be determined. I noticed that you are using Excels Countif function to generate the frequency values. 2. This kind of graph uses vertical bars to display quantitative data . At present I do this manually by calculating the probability density function and scaling it with the factor (sample size)*(bin size) based on the observation that the area under the histogram is Sum(ni * (bin size))=Sum(ni)*(bin size)=(sample size)*(bin size). The bottom axis ranges start with the lowest number. Click the "Insert Statistic Chart" button to view a list of available charts.
