High-density line sampling [ERROR] ?

Hi everyone,

I'm confused about the High density sampling (HDS) algorithm. I've got a Line Chart with 57 different series with the sampling of every 10 minutes from 5 AM to 10 PM. So, the total data points are 57*6*17 = 5814. The documentation about High Density (Line) Sampling indicates that the maximum number of series that can be displayed is 60 and data points is 3500 for high density sampling.

Specifically:

 

Below are two screenshots, first one with HDS Off, second with HDS On:

It can be seen that as I am turning ON HDS, it is taking off the outlier, which is of utmost importance.

Also, if keep the HDS off and decrease the data points below 3500 by taking less timestamps, the box doesn't shows information for all 57 series. Screenshot attached below:

Again, information showed here is of no use, as the outlier identity is still unknown.

Anyone in the community, please have a look into this probem and provide guidance. 
I appreciate everyone's time and efforts.

Thanks.

As you have seen your data exceeds the 3500 limit.  Use less data or create separate visuals
