3. In the two cells below Y cell, type 0 and 1 in each cell. See screenshot:

5. Then right click at the bar chart, and click Select Data from context menu
6. In Select Data Source dialog, click Add button in the Legend Entries (Series) section.
7. In the Edit Series dialog, type the new series name you need, and select B11:B12 (B11:B12 is the range you calculate average in step 4).
8. Click OK > OK to close dialogs. Then select the new series you added in the bar chart, and right click to click Change Series Chart Type in context menu.
9. In the popped out Change Chart Type dialog, select X Y (Scatter) > Scatter with Straight Lines, and click OK to exit the dialog. See screenshot:
In Excel 2013, select Combo section under All Charts tab, and select Scatter with Straight Lines from the drop down list in Average series, and click OK to exit the dialog.
10. Go to the chart and right click to click Select Data in the context menu again.
11. In the Select Data dialog, select Average series and click Edit button.
12. In Edit Series dialog, select the X values and Y values range. (You just need to add the range cells below Cell Y and Cell X you have typed in step 2 to Y values and X values.)
13. Click OK > OK to close dialog. Then right click at the right Y axis (the secondary axis), and select Format Axis from the context menu.
14. In the Format Axis dialog, check Fixed option after Maximum and then type 1 into the textbox beside the Fixed option.
In Excel 2013, you just need to directly type 1 into Maximum text box in the Format Axis pane.
15. Close dialog. Now the average vertical line has added into bar chart.
You can format the line by right clicking the line and selecting Format Data Series in the context menu, then you can change the line as you need in the Format Data Series dialog/pane.
