Sample document that have two independent rows with numbers and sparkline
See attached spreadsheet.
In sparkline group editor, the "High points" is set to a black-like color.
However, it seems that the visible output on screen, that setting is ignored.
Instead of the bar representing the highest value (all negative, so the one that i closest to zero must be regarded as "High value") being black (or any color given) - it just remains the same color as for sparkline series.
