Describe the bug: When you chose a stacked line graph, the line for one of the terms is drawn correctly, while the other is drawn incorrectly as 100%.

Steps to reproduce:

Create a date histogram using a terms agg as a sub aggregation.

Switch from bar to line in Chart Type
Switch from normal to stacked in Mode

The true line is drawn incorrectly as 100%

Normal Mode:

Stacked Mode:

Expected behavior:

Similar to the bar version of the graph:

That's actually "expected behavior". Stacking line charts, (without enabling areas) usually doesn't make much sense in the terms of data visualizations. Stacking makes sure, that not all series are drawn from "the bottom" of the chart, but are drawn on top of the previous series (as it's pretty well shown in the bar chart). If you use lines, it doesn't really make sense to use that, because due to the lack of "filling" of the lines, it's pretty confusing, that the 2nd line is now drawn on top of the first line. But the outcome is perfectly fine. The output will always just be the line, that connects the top of the bars in the stacked bar chart.

I will close this since this is desired behavior, though we def will make sure in the new visual editor (#17076) that users can't shot themselves in their foot using senseless chart configurations.

The issue is not the stacked line chart but the normal line chart... It's acting like its stacked and not starting the lines from the bottom of the chart.
