I have to create a chart that has three columns that I would like to show as
two bars,the columns are one with a fixed amount and the other two with a
negative to positive range. Do you know how this could be done?

Ive included a sample of the data, the first numeric column would be the
first set of bars (2.5, 8.9, etc.) and the second two columns would be the
range set of bars (-5.3 to 10.3, etc.)

Sample 1 2.5 -5.3 10.3
Sample 2 8.9 -2.5 20.3
Sample 3 3.8 -7.4 14.9
Sample 4 0.0 -7.1 7.1

Any help would be greatly appreciated! Thanks!!!!
