Please refer to the attached sample project. Try to select a point.
Expected result: the clicked point should be colored in red.
Actual result: a random point is colored in red even though the label is colored correctly. The attached gif file illustrates the observed result.

Hi team,
We need a ChartView with multiple series and multiple Y-axis. The axis color of each Y-axis should be automatically painted according to the palette setting (thank you for the brilliant work - it's very intuitive). However, if clear the series and re-assign a new set of series, the border color of the first axis changes to black, regardless which palette is active. If the palette is set to a new one, the border color can be re-painted correctly. See screenshot as attached.
How to reproduce: Please refer to the attached project for a demo of reproduction. Click the first button to populate new random data. The border color of the first axis should change to black after clicking the button twice and more times. Clicking the second button will force the palette to change and the border color will become normal.
Thank you, team.
Best,
Yusi
When you have BarSeries and LineSeries in RadChartView the problem is that the DataPoint.Presenter is always BarSerries, never LineSeries.
To workaround, create custom renderer:
this.radChartView1.CreateRenderer += this.RadChartView1_CreateRenderer;
private void RadChartView1_CreateRenderer(object sender, ChartViewCreateRendererEventArgs e)
{
e.Renderer = new CustomCartesianRenderer(e.Area as CartesianArea);
}
public class CustomCartesianRenderer : CartesianRenderer
{
public CustomCartesianRenderer(CartesianArea area)
: base(area)
{ }
public override DataPoint HitTest(int x, int y)
{
for (int i = this.DrawParts.Count - 1; i >= 0; i--)
{
DataPoint dataPoint = this.DrawParts[i].HitTest(new Point(x, y));
if (dataPoint != null)
{
return dataPoint;
}
}
return base.HitTest(x, y);
}
}
Use attached to reproduce.
- Click at least 7 times.
Workaround: Crete new series instance each time.
Inside the constructor of a form create a pie series and populate it with data. Then add it to a RadChartView. You will notice that there are two legend items per data point.
Use attached to reproduce.
Workaround:
series.DataPoints.Add(new PieDataPoint(0.01, "Germany"));
To reproduce: - Just add StochasticSlowIndicator to a chart.
To reproduce: 1. Perform zoom and pan operation and click the print/print preview button: 2. You will notice that the printed chart is not exactly the same as the displayed one. Please refer to the attached screenshot. public Form1() { InitializeComponent(); LineSeries lineSeries = new LineSeries(); lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan")); lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr")); lineSeries.DataPoints.Add(new CategoricalDataPoint(12, "Jul")); lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct")); this.radChartView1.Series.Add(lineSeries); LineSeries lineSeries2 = new LineSeries(); lineSeries2.DataPoints.Add(new CategoricalDataPoint(18, "Jan")); lineSeries2.DataPoints.Add(new CategoricalDataPoint(15, "Apr")); lineSeries2.DataPoints.Add(new CategoricalDataPoint(17, "Jul")); lineSeries2.DataPoints.Add(new CategoricalDataPoint(22, "Oct")); this.radChartView1.Series.Add(lineSeries2); ChartPanZoomController panZoomController = new ChartPanZoomController(); panZoomController.PanZoomMode = ChartPanZoomMode.Horizontal; radChartView1.Controllers.Add(panZoomController); } private void radButton1_Click(object sender, EventArgs e) { this.radChartView1.PrintPreview(); } 3.The issue also appears when the LassoZoomController is used.
After 1 million the decimal places of the labels are not correct, In your image. the labels on the horizontal axis go 999,992.50 - 999,995.00 - 999,997.5 - 1,000,000.00 - *1,000,003.00(should be 1,000,002.50) - 1,000,005.00 - *1,000,008.00(should be 1,000,007.5)
To reproduce: - Add a chart to the form and set series with DataSource - Close and dispose the form Workaround: Set the DataSource property of the series to null prior closing.
