why the zero data shows in pivot table but not showing in a straight table and line chart?

Hi Guru,

Any one can help on this chart? below line chart doesn't show week 1 value (which should be zero)

If I switch it to pivot table, it will show the week 1 value. Why???

Here is the expression: so basically I compare each week value increase % or decrease % against week 1 value.

I have figured out why... Need to untick suppress zero value in the presentation tab.
