How to Use Line and ScatterPoint Palette?

[Ingrid]

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:

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