I got the following table on google sheets.

I want the first column to represent the groups in x axis. The 2nd column is supposed to be the a group in a certain x value lets say I have

8 3 22

8 4 55

8 5 72

I want to have at value x = 8 , 3 bars, the first bar has the y value of 22 with the label 3, the 2nd has y value of 22 with label 4, and the 3rd has y value of 72 with label 5.

This is the chart I got which is completely not the one I wanted.
