in V7, it seems that the gridline is always the same color as the custom tick.
Code: Select all
axis.CustomTicks.Add(new CustomAxisTick(axis, point.Value, point.Label ?? string.Empty)
{
Color = Colors.Black,
Style = CustomTickStyle.TickAndGrid,
Length = 5,
});
In v6 the custom ticks and gridlines settings were taken from the normal ticks.
