Issues in showing the horizontal axis label of secondary axis

[logstarter]

Hi,

i am trying to follow the following tutorial to create a clustered stacked column bar chart. In step 3 of fixing the axis, I had set the horizontal axis label of secondary axis in the "Select Data Source". But even I set that, the horizontal axis doesn't show it in the upper part of the chart... I would like to ask i need to set anything else?
