Greetings,
Is there a way to make a Candle Stick HighLowPen.Color the same as the Stick color.
example ...

You can see that the HigLowPen's color is the same as the rest of the candle.
I looked at this example "Welcome !\Chart styles\Financial\Candle (OHLC)\Candle HighLow pen" but it only covers changing ALL the HigLowPen's to one color.
Failing that .. I guess I'll have to color each HigLowPen individually .. any suggestions on where is the best place to do this ... or do I need to do a separate iteration through the Candle series once its drawn ...
Cheers Phil.

Hi Phil,
You could use GetPointerStyle event to change the series Pen.Color before drawing each point:
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
Steema.TeeChart.Styles.Candle Candle1 = new Steema.TeeChart.Styles.Candle(tChart1.Chart);
Candle1.FillSampleValues(10);
Candle1.CandleWidth = 15;
Candle1.UpCloseColor = Color.Green;
Candle1.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(series1_GetPointerStyle);
}
void series1_GetPointerStyle(Steema.TeeChart.Styles.CustomPoint series, Steema.TeeChart.Styles.GetPointerStyleEventArgs e)
{
series.Pointer.Pen.Color = e.Color;
}

Greetings .. back again ... did you miss me? no ?? oh well
On the topic of Coloring candles ... with your kind support I have them looking pretty much as I want them ..

And happily whatever color the candle is, so is the PointerStyle color ... perfect ...
However ... the candle coloring happens thanks to the
Code: Select all
myCandle.Style = CandleStyles.CandleStick;
myCandle.UpCloseColor = Color.Green;
myCandle.DownCloseColor = Color.Red;
Now when the
close price == the
open price we like to color our candles
grey ... is there a way to color random candles ?
I tried this but just got multicolored Candles ... very pretty .. not so usable
Code: Select all
for (int index = 0; index < dataList.Count; index++)
{
double open = Convert.ToDouble(dataList[index].Open);
double high = Convert.ToDouble(dataList[index].High);
double low = Convert.ToDouble(dataList[index].Low);
double close = Convert.ToDouble(dataList[index].Close);
DateTime idate = dataList[index].Date;
// Labels for the X axis.
labels.Add(idate.ToShortDateString());
/// Color the pointers for the Candles
Color pointerColor;
if (open > close) pointerColor = Color.Red;
else if (close > open) pointerColor = Color.Green;
else pointerColor = Color.DarkGray;
myCandle.Colors[index] = pointerColor;
// Add the data to the Series.
myCandle.Add(index, open, high, low, close);
}

Hi Phil,
If I understood well, you should use again the GetPointer event:
Code: Select all
private void InitializeChart()
{
tChart1.Aspect.View3D = false;
Steema.TeeChart.Styles.Candle Candle1 = new Steema.TeeChart.Styles.Candle(tChart1.Chart);
Candle1.CandleWidth = 15;
Candle1.Style = Steema.TeeChart.Styles.CandleStyles.CandleStick;
Candle1.UpCloseColor = Color.Green;
Candle1.DownCloseColor = Color.Red;
//testing values
Candle1.FillSampleValues(10);
Candle1.CloseValues[2] = Candle1.OpenValues[2];
Candle1.GetPointerStyle += new Steema.TeeChart.Styles.CustomPoint.GetPointerStyleEventHandler(series1_GetPointerStyle);
}
void series1_GetPointerStyle(Steema.TeeChart.Styles.CustomPoint series, Steema.TeeChart.Styles.GetPointerStyleEventArgs e)
{
if (series is Steema.TeeChart.Styles.Candle)
{
Steema.TeeChart.Styles.Candle candle = series as Steema.TeeChart.Styles.Candle;
if (candle.CloseValues[e.ValueIndex] == candle.OpenValues[e.ValueIndex])
e.Color = Color.Gray;
}
series.Pointer.Pen.Color = e.Color;
}
