Problem with Fiscal Yr.Period label display in Chart

Hello Experts,

I have Fiscal Yr.Period in the x-axis of Chart component. In Initial View, I have set Key for Fiscal yr.period. But the label in chart shows like "K4001.2014" which is a compounding of Fiscal Yr.variant.

Any idea on how to remove the Fiscal Yr.variant in the chart label.?

Thanks & Regards,

Kesavan.
