rcheskin The problem is with the large data points, when you select multiple values from the slicer like brand 1 and brand 2, you will see an icon like i on the visual, and that explains it is showing sample data points and in that case, the starting point for reference line is getting removed. You can check that by clicking the show as a table as shown in the image below, and you will see in the table when multiple brands are selected the data point for 20hz for the reference line disappears. I hope it helps.

    Thanks for the insight - are there any workarounds other than modifying the underlying data for the Reference Curve?  When I eyeball the table data, the Reference has significantly fewer data points compared to the other products, so it appears the sampling is favoring the other lines.  I also find it strange that the sampling algorithm does not include the minium values in the data set by default.
