I have the following data set of 12 numbers that make up landmarks. 5,,7,7,7,8,9,10,14,15,15,16,16,17,18. How do I display them on a bar graph?

Horizontal axis (X axis, abscissa) is the values of the scores, while the vertical axis (Y axis, ordinate) would indicate the frequency of each score.

I hope this helps.
