I have a RadPieChart in my application. When removing the app from the backstack and service is running, then opening the app from the notification, the app crashes with:
Java.Lang.IllegalStateException: ChildNode is already parented by a ChartElement instance.
When adding a plot band annotation to the date time axis, it is not applied on MacCatalyst and iOS. In addition if using binding, an exception is thrown.
System.ArgumentNullException: Value cannot be null.Parameter name: minimum
at TelerikUI.TKRange..ctor (Foundation.NSObject minimum, Foundation.NSObject maximum)
It works on Android and WinUI
An exception is thrown when setting the ChartPallete FillColor property. The issue is reproduced on all platforms.
Workaround:
Also set the StrokeColor property.
<telerik:ChartPalette>
<telerik:ChartPalette.Entries>
<telerik:PaletteEntry FillColor="Red" StrokeColor ="Yellow"/>
<telerik:PaletteEntry FillColor="Gray" StrokeColor ="Yellow" />
<telerik:PaletteEntry FillColor="Blue" StrokeColor ="Yellow"/>
</telerik:ChartPalette.Entries>
</telerik:ChartPalette>
Hi team,
Currently, I can only set LegendItemFontColor and LegendItemFontSize. I would like to be able to set LegendItemFontFamily
Thank you,
John
Hi Team,
I would like to be able to set different cap styles on the bars, like the RadGauge allows you to do on Indicators. For example, I want rounded corners.
Thank you,
John
On some chart series like, bar, line, scatter line, etc, the y axis line is hidden. make it visible, as it is on Android and Windows.
Current solution is to use the chart handler changed and set YAxis.Style.LineHidden to false.
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
this.chart.HandlerChanged += this.Chart_HandlerChanged;
}
private void Chart_HandlerChanged(object sender, EventArgs e)
{
this.UpdateChart();
}
private void UpdateChart()
{
var platformView = this.chart.Handler.PlatformView;
#if IOS || MACCATALYST
var platformChart = (Telerik.Maui.Controls.Compatibility.ChartRenderer.iOS.TKExtendedChart)platformView;
platformChart.YAxis.Style.LineHidden = false;
#endif
}
}
Add an option to define chart title.
Currently we can achieve this by adding a label on the top/bottom of the chart.
Example:
<Grid RowDefinitions="Auto,*">
<Label Grid.Row="0" Text="Chart title"/>
<telerik:RadCartesianChart x:Name="chart" Grid.Row="1" AutomationId="chart">
<telerik:RadCartesianChart.BindingContext>
<local:ViewModel />
</telerik:RadCartesianChart.BindingContext>
<telerik:RadCartesianChart.HorizontalAxis>
<telerik:CategoricalAxis />
</telerik:RadCartesianChart.HorizontalAxis>
<telerik:RadCartesianChart.VerticalAxis>
<telerik:NumericalAxis />
</telerik:RadCartesianChart.VerticalAxis>
<telerik:RadCartesianChart.Series>
<telerik:BarSeries CategoryBinding="Category"
ValueBinding="Value"
ItemsSource="{Binding Data}" />
</telerik:RadCartesianChart.Series>
</telerik:RadCartesianChart>
</Grid>
I would like to use line style instead of colour to distinguish between the different series on my chart as below.
Is this possible?
From the docs it looks like we can only customise stroke colour and thickness.
Thanks =)
Can the Legend be identical to the LineSeries, not only by colour, but also by style?
Can I customize the text inside the bar?
- Text Color, Position, FontSize, etc.
