Labels
If you want Labels to come on top of each bar, you can add them by clicking on Component Properties > Labels.
You can select the Label to appear either on Top or Bottom.
Label Series will be either the X or Y axis names.
Label orientation will allow you to change the position of the labels appearing on the bars : Middle, Left or Right.
