Hello Everyone,

I have a somewhat simple graph using a combo Bar + Line chart.

This is my data, the date column goes back to October 1st.

This is my chart, so for, so good.

Then, to have my lines to fill the chart I am selecting "On tick marks" for the X axis.
And then somehow Excel breaks the chart.

To make it even worse, Excel is plotting the data completely outside the chart area

I have never seen something like this before, I have tried recreating this from scratch so many time and the result is always the same, I don't know what could be causing this.

Thank you very much.
