I have a range of data that is listed in a column. I need to plot this data
in terms of numbers of observations. For instance, the column reading down
has the following points:

0.77
0.68
0.68
0.65
0.65
0.65
0.60 and so on...

The values are sorted from highest to lowest and there are 130 data points.

I need the data values on the y-axis and the number of times the value
occurs on the x-axis. Can anyone offer advice? Thank you.
