wpf graph scale with dynamic ticks

[eugenem]

I need to increase number of major divisions to at least 10, but such that min and max will still be dynamic, e.g. grid would move along with the plot.

If I force <ni:RangeLabeledDivisions TickVisibility="Hidden" Mode="Count: 11">, then number of cells is the same, but plot is not moved independent of the grid, and grid labels show non-pretty numbers.

If I don't force mode, then grid behaves very well, but it uses about 3.5 divisions

Major tick values are controlled by the GetDivisions method on RangeDivisionsMode, which receives an estimate of the number of divisions that will fit on screen. A simple workaround to increase the number of auto-generated divisions would be to pass a different estimate to the Auto implementation:

    public sealed class CustomDivisionsMode : RangeDivisionsMode {
        public override string Name {
            get { return "Custom"; }
        }
        public override bool RequiresDivisionsEstimate {
            get { return Auto.RequiresDivisionsEstimate; }
        }
        public override IList<TData> GetDivisions<TData>( IRangeDataMapper<TData> mapper, int divisionsEstimate ) {
            return Auto.GetDivisions<TData>( mapper, divisionsEstimate * 2 );
        }
        public override IList<TData> GetSubdivisions<TData>( IRangeDataMapper<TData> mapper, IList<TData> dependentDivisions ) {
            return Auto.GetSubdivisions<TData>( mapper, dependentDivisions );
        }
    }
