Line Chart with 2 dimensions looks wrong

[#1]

Can someone help me think of a way to fix this?

I have a line chart with two dimensions, Month and Day. I am displaying Month on the bottom and Day on the top.

My first expression is sum(Revenue).

My second expression is just 0 (hidden), to force both dimenions onto the X-axis.

However, my line chart is not spanning across the days. Instead, all of the values are displayed on top of the Month value (See pic, see attached qvw example).

Anyone know how to fix this or work around it?
