XY chart empty Y value shows up as 0

When using a table as input to xy chart empty Y values are shown as 0. My question is how to not show the values that are empty in the chart?
P_MW = X value. the other column is the Y value.

there is a transformation you can use, filter data by values, you can exclude nulls, 0 values etc.


Hi, we tried with this, but it doesn’t work. Can it be because it expect all values to be 0 in a serie?
