Non-continuous line chart data

Hi,

I have a table consisting of a date with four value columns which I've charted. Here:

I may not have all four values for every date, and when this happens, I don't want that part of the line to render. Excel handles this as I would like:

Is there any way of configuring Power BI not to interpolate and render a line for missing data?

Also; I've noticed that the 'values' for a chart always have some sort of aggregation (Sum, Count, Avg, etc). Is it possible to just chart the raw data values?

Thanks,

Ciarán
