Describe the bug:
In the Time Series Visual Builder, axis min value automatic scaling is not working when a filter is applied. Instead of binding to the data, it reverts to zero.

Steps to reproduce:

1. Plot a line graph with Time Series Visual Builder without specifying axis min and axis max value.

2. Apply a filter on your data, either with panel options->panel filter, or with control vizualization (experimental).

Expected behavior:

1. Works as expected without filter. The scale automatically adjusts to the data both for min and max with a padding. It results in a nice "zoomed in" vizualization.

2. Does not work with a filter applied : y axis max adjusts fine binding to the data but the y axis min value starts at 0 instead of binding to the data filtered.

In the example above, the y axis min value should start somewhere around 1000 not 0.

This affects user experience who cannot see clearly changes due to improper automatic scaling for the y min axis as seen on the screenshot above.

Errors in browser console (if relevant):
N/A

Provide logs and/or server output (if relevant):
N/A

Any additional context:
This behavior was not seen on Kibana 7.3.1. We are facing this issue after updating to 7.5.0

Thank you
