I have a chart with three series with a DateTimeAxis on the y Axis. Coloring works fine for the three series.
However, I'm trying to reverse the order on the y axis by adding data points with negative milliseconds (I checked one of the values and it corresponds to a date in 1925). This makes the chart ignore the line colors I'm setting and use default line colors.
I tried charting both negative and positive values and the positive ones showed with the correct colors, while the negative values (the dates with the negative millis) show with a different color.
How do I make this work with charting dates before Epoch?
