[WPF] Columns from ColumnSeries disappear from chart if Y axis is zoomed too much

User cant set MaxLimit on Y axis below particular level, otherwise columns are not visible.

Steps to reproduce the behavior:

1. Add ColumnSeries and Y axis to the chart

        public IEnumerable<ISeries> Series { get; set; } = new ObservableCollection<ISeries>
        {
            new ColumnSeries<double>
            {
                
                Values = new ObservableCollection<double> { 5,6,7,8,5,6,7,8 },       
            }
        };

        public List<Axis> YAxes { get; set; } = new List<Axis>
        {
            new Axis
            {
                IsVisible = true,
                MaxLimit = 20,
                MinLimit = 0,
                ShowSeparatorLines = false,

            }
        };

1. Add function allowing you to change MaxLimit

        public void Zoom()
        {
            YAxes[0].MaxLimit *= 0.8;
        }

1. Columns should be visible

2. Call Zoom function several times. Columns shrink and disappear

Expected behavior Changing MaxLimit should not affect columns visibility

Well, I think I didnt desrbice it clear enough. I was talking about situation when you have zooming and panning disabled and you keep MaxLimit on Y axis defined. Its because you want specific Y range.

I Agree, but notice in your image, that the library respects your range in the Y axis, but because you don’t have a a range the X axis, then the library is trying to fit the view to the current data, since you have no points in that Y range, then the X axis messes up.

I think that the library should be smarter, and maybe use the previous valid range if the new one is not valid.
