is there a way to give every endpoint on a chart line a other color or read the details of the point so i can draw the point into an canvas overlay. The you see in the chart is a team pursuit. The point is the fastest athlete on track. See the table. I want to change the color of the point. If there is a mouse over function with x and y from the point i can draw the data in a canvas on top (see big yelow DOT)
seems not possible in xojo to change a single datapoint color at linear dataset.
maybe add another Dataset for fastest (or 1,2,3) athlete on track.
ChartScatterDatapoint have a radius propertie.
