To reproduce:
- Use HTML- like text formatting in the chart title.
- Export the chart to image.
- The tags are shown in the text.
Workaround:
private void radButton1_Click(object sender, EventArgs e)
{
radChartView1.ShowTitle = false;
TextPrimitiveHtmlImpl impl = new TextPrimitiveHtmlImpl();
TextParams textParams = this.radChartView1.ChartElement.TitleElement.TextParams;
SizeF size = impl.MeasureOverride(new SizeF(500f, 200), textParams);
using (MemoryStream stream = new MemoryStream())
{
radChartView1.ExportToImage(stream, new Size(500, 500 - (int)size.Height));
Bitmap bmp = new Bitmap(500, 500);
using (Graphics g = Graphics.FromImage(bmp))
{
g.Clear(Color.White);
textParams.paintingRectangle = new RectangleF(Point.Empty, size);
impl.PaintPrimitive(new RadGdiGraphics(g), textParams);
g.DrawImage(Image.FromStream(stream), 0, size.Height, 500, 500 - size.Height);
}
bmp.Save(@"D:\xfile.bmp");
}
radChartView1.ShowTitle = true;

When combining scalebreaks and series stacking, the rendered chart does not match the data. See attached solution: The bar of the category "1/2016" has a length of 105 (as indicated by the tooltips) -- but the corresponding axis labeling shows a value of 37. The scalebreak is off too (probably matching the wrong axis).

To reproduce:
- Enable the Trackball
- Use the following code:
public RadForm1()
{
InitializeComponent();
ScatterLineSeries sls = radChartView1.Series[0] as ScatterLineSeries;
sls.XValueMember = "X";
sls.YValueMember = "Y";
}
private void timer1_Tick(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("X", typeof(double));
dt.Columns.Add("Y", typeof(double));
Random ran = new Random();
for (int i = 0; i < 100; i++)
dt.Rows.Add(i, 1 + ran.NextDouble() / 10);
radChartView1.Series[0].DataSource = dt;
}
Workaround:
class MyChartTrackballController : ChartTrackballController
{
protected override string GetPointText(DataPoint point)
{
ChartSeries series = point.Presenter as ChartSeries;
if (series == null)
{
return string.Empty;

return base.GetPointText(point);
