    Hello,

    I have 3 chart series on my page, bar, line, and scatterpoint.
    I successfully make the bar to be coloured (5 colours) as i programmed. But there is no PaletteMode property on LineSeries and ScatterPointSeries.
    Why and How the code should be?

    Here is my code,
    this code only make the line and scatterpoint series 1 color, while my _viewmodel.CustomPalette has actually 5 colours (with 5 items).

     

     

    01.void setChartData()
    02.{
    03.    chartView.Children.Clear();
    04. 
    05. 
    06.    string itemSource = "_SummaryList";
    07.    string categoryBinding = "Short_Name";
    08.    string valueBinding = _viewmodel.ChartValue;
    09. 
    10.    var hAxis = new CategoricalAxis();
    11.    hAxis.LabelFontSize = 6;
    12. 
    13.    var vAxis = new NumericalAxis();
    14.    vAxis.LabelFontSize = 7;
    15.    vAxis.LabelFormat = "#,#.#";
    16. 
    17.    var chart = new RadCartesianChart
    18.    {
    19.        HorizontalAxis = hAxis,
    20.        VerticalAxis = vAxis,
    21.        VerticalOptions = LayoutOptions.FillAndExpand,
    22.        HorizontalOptions = LayoutOptions.FillAndExpand
    23.    };
    24. 
    25.    switch (_viewmodel.ChartType)
    26.    {
    27.        case "Bar":
    28.            var bar = new BarSeries();
    29.            bar.SetBinding(ChartSeries.ItemsSourceProperty, new Binding(itemSource));
    30.            bar.ValueBinding = new PropertyNameDataPointBinding(valueBinding);
    31.            bar.CategoryBinding = new PropertyNameDataPointBinding(categoryBinding);
    32.            bar.PaletteMode = SeriesPaletteMode.DataPoint;
    33.            bar.ShowLabels = true;
    34.            chart.Series.Add(bar);
    35.            chart.Palette = _viewmodel.CustomPalette;
    36.            break;
    37.        case "Line":
    38.            var lines = new LineSeries();
    39.            lines.SetBinding(ChartSeries.ItemsSourceProperty, new Binding(itemSource));
    40.            lines.ValueBinding = new PropertyNameDataPointBinding(valueBinding);
    41.            lines.CategoryBinding = new PropertyNameDataPointBinding(categoryBinding);
    42.            lines.ShowLabels = true;
    43.            chart.Series.Add(lines);
    44.            chart.Palette = _viewmodel.CustomPalette;
    45.            break;
    46.        case "Point":
    47.            var point = new ScatterPointSeries();
    48.            point.SetBinding(ChartSeries.ItemsSourceProperty, new Binding(itemSource));
    49.            point.YValueBinding = new PropertyNameDataPointBinding(valueBinding);
    50.            point.XValueBinding = new PropertyNameDataPointBinding(categoryBinding);
    51.            point.ShowLabels = true;
    52.            chart.Series.Add(point);
    53.            chart.Palette = _viewmodel.CustomPalette;
    54.            break;
    55.    }
    56. 
    57.    chartView.Children.Add(chart);
    58.}

    Hi Ingrid,

    Indeed, PaletteMode property is available only for BarSeries.  Actually, I am not sure how such a property would be applicable to LineSeries, could you elaborate more on this?

    As to the ScatterPointSeries - I would suggest you log a feature request for this in our public feedback portal at the link below:
    https://feedback.telerik.com/Project/168/Feedback/List/All%20Feedback

    In this way we could track the demand and plan it accordingly.
