Candle HighLowPen coloring.

[Snarkle]

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;
        }

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;
        }
