Sparkline with database source examples


Is there an example of how to use database as a datasource for a sparkline in an angular project?

All i get is a vertical bar, it almost looks like its either only taking the last value or they superimpose over each other

i've tried changing the expression to ${getMyViews.ValColumn} and leaving the data property blank but then the sparkline doesnt appear at all

I know the data is coming in because i created a datagrid on the same page and fed it the same get call. It shows the rows i'm trying to show in the sparkline
