Let's assume your data are in cells A1:A11 (as above).
First, use a combination of the SORT and UNIQUE functions to create a list of each unique value in your data. For example, you could put the formula =SORT(UNIQUE(A1:A7)) in cell B1 to create the list. The resulting list will have four values (95, 96, 97, 100) in, say, cells B1:B4.
Then, use the FREQUENCY function to get a count of the number of occurrences of each value. The FREQUENCY function takes two range arguments: the data range and the class range. The class range is the values for which you want the frequencies calculated, which in this case would be in cells B1:B4. Assume you've entered the FREQUENCY function in cell C1.
Now create a chart using the range B1:C4 as input. When you specify the chart, be sure to check "Use column B as labels". The setup and a possible chart are shown below.
