Show zero values in Line Chart report in Report Studio

[stancho]

Hello,

I have DMR model and outer join between fact table and Date Dim in order to show all of the dates even there is no data for them.
I show the measure in a Line Chart. How to get zero values where there is not data. Currently the line is being broken where there is no value.

I need something like "formatting on the cells in crosstab set the "missing value" to show as 0" but for chart.
This is working for a crosstab but no for a chart.

Thanks,
Stancho
