....I thought the 'lines drawn' are perpendicular to each axis. So, while the "446 horizontal pixels" makes sense, as how far across to draw; the '286' is how many horizontal lines are drawn. That is, on a graph, lines drawn on the X axis are *vertical*....
Consider it high comedy....sincere tragedy....whatever...don't take it personally.
