Line and Stacked Column Chart not working as expected

Hi Freemanz,

I am trying to create line and stacked column chart using the above table but the chart is not stacking up. But when I used same data for Line and culstered column chart it works fine.

I use Year-Month in Shared axis, and type in column series, revenue in column values and at last I see account in line values.

still I don't see my stacked chart working as expected.

But I want to do line and stacked column chart. Please help 

Thanks
