xAxis Label

[LengTrang]

Hi, I am working on a project that utilizes your amazing Barchart system. I encountered a situation I am hoping the community can assist me on.

I have a a list of two Months, February to March.
For Data we have 31 days.
I have values on February 14, and March 14.
If I have just the days stored. 1-13, There's no way to know if it's March 14 or February 14.
The Indices for XAxis Listed are "14, 21, 28, 7, 14". As you can see, you can not tell what month it us. When I select, March 14, The system only see's 14, and will pick Feb 14, not March 14.
I changed the Indice tobe:
"Feb 14, Feb 21, Feb 28, Mar 7, Mar 14" For the labels under chart. Unformately my team wants just number. While this works but the team want the labels to behave as before.

Does anyone have ideas of what I can do in this framework? I looked for properties I can access but nothing public can be used without causing other unwanted behavior. I am hoping someone more familiar with the framework can offer suggestions. Thank you in advance for those are able to help.
