I am drawing a Line Chart (UltraWinChart) with only a single point at the end (all the rest are NULL values specified as "don't draw").  Unfortunately, the begin and end points in a Line Chart are not being drawn as points.  No matter how much I bump up the line thickness, these points can't be seen in the graph (even when you hover over them the tooltip only shows as the numeric value with a left-crecent (of the circle that's supposed to be indicating the point you're tip is about)

Is there a way to 'show' the begin/end points [i.e. make them be rendered all the time] in a Line Chart?
