Multiple Values in X-Axis

Hi, 

Curently I am using Lined and CLustered chart where x-axis is used to represent dates. Now i want to add one more field to it so that x -axis drive by both fields in form of group like below

Even though i am able to aadd this new field above or below the Date field in SHARED AXIS  field still its not showing up in the chart.

Any help?

So basically Primary Grouping is based on A,B and C and Secondary based on dates

Cheers,

RDS
