Ok. And thank you very much for this feedback.
Best regards!

Hi Konstantin,

Kagi charts ignore the passage of time and the time axis of a Kagi is not linear. For this reason it is not possible to place a Kagi chart on the same X-axis with a Line or Stock chart. You can still place a Kagi and a Line series in the same chart, but you have to use different X axes (if this makes sense).

The general problem is in foloowing: I need to display different types of series on the same chart.

I modified NKagiUC.cs file in Nevron.Examples.Chart.Winform by adding one more NLineSeries to the chart:

please see the main code from Initialize() method:
public override void Initialize()
{
base.Initialize();

NChart chart = nChartControl1.Charts[0];

// setup X axis
NPriceScaleConfigurator priceConfigurator = new NPriceScaleConfigurator();
priceConfigurator.InnerMajorTickStyle.LineStyle.Width = new NLength(0);
priceConfigurator.InnerMajorTickStyle.LineStyle.Color = Color.Green;
priceConfigurator.InnerMinorTickStyle.LineStyle.Width = new NLength(0);
chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = priceConfigurator;

// setup Y axis
NLinearScaleConfigurator linearScale = (NLinearScaleConfigurator)chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator;
NScaleStripStyle stripStyle = new NScaleStripStyle(new NColorFillStyle(Color.Beige), null, true, 0, 0, 1, 1);
stripStyle.Interlaced = true;
stripStyle.SetShowAtWall(ChartWallType.Back, true);
linearScale.StripStyles.Add(stripStyle);

// setup Kagi series
NKagiSeries kagi = (NKagiSeries)chart.Series.Add(SeriesType.Kagi);
kagi.UpStrokeStyle.Color = Color.MidnightBlue;
kagi.DownStrokeStyle.Color = Color.MidnightBlue;
kagi.UseXValues = true;

// add a line series
NLineSeries line = (NLineSeries)chart.Series.Add(SeriesType.Line);
line.Name = "Line Series";
line.DataLabelStyle.Visible = false;
line.UseXValues = true;

GenerateData(kagi, line);
}

and GenerateData method does following:

private void GenerateData(NKagiSeries series, NLineSeries lineSeries)
{
NStockDataGenerator dataGenerator = new NStockDataGenerator(new NRange1DD(50, 350), 0.002, 2);
dataGenerator.Reset();

DateTime dt = new DateTime(2008, 2, 1);

for(int i = 0; i < 100; i++)
{
var nextValue = dataGenerator.GetNextValue();

series.Values.Add(nextValue);
lineSeries.Values.Add(nextValue);

series.XValues.Add(dt);
lineSeries.XValues.Add(dt);

dt = dt.AddDays(1);
}
}

On the XAxis I get showing of 1899 year that really is not referenced to any NKagiSeries or NLineSeries.
And I use "UseXValues = true" for both types of series.

And there in no any problem with separate displaying of the one series type (NKagiSeries or NLineSeries) on the chart.

It seems there is some bug or problem with "UseXValues = true" for NKagiSeries when it is used in couple with some other series type.

I am new in Nevron. And I will be appreciate for any feedback.
Thank you.

Konstantin.
