Invalid metric using None for the Aggregation
I'm trying to plot data collected in a Sheet vs time. Time appears as the Dimension (correctly). Columns are Additional Dimensions. Setting Aggregation to None forces a column (Chip color = green) to be a Dimension. However, I don't want any form of Aggregation for the columns - I just want to use the raw Sheet data for the plot. But I can't. In the screengrab below, Outside Air Temp becomes a second Dimension because it's Aggregation is set to None. In fact I want Outside Air Temp to be a plotted value using raw data directly from the Sheet.
Even using Aggregation = Average produces a weird plot. In the example below there are no zero values in the data - but the plot shows them.
What am I doing wrong? Or is Studio incapable of handling raw data?
