  Hi! Can i change color of candlestick? For example, “green” color for bullish candlesticks and “red” color for bearish candlesticks, w/o border line.

  Hi,

  In order change color of candles(data points) based on saome condition(e.g. for bullish Close>Open) you can make use of Series.SymbolRendering event. In the event handler, you can set Fill/Stroke brushes for chart rendering engine as follows:

  private void Series_SymbolRendering(object sender, C1.WPF.Chart.RenderSymbolEventArgs e)
  {
   var dataItem = e.Item as DataItem;
   Brush brush = dataItem.Close > dataItem.Open ? Brushes.Green : Brushes.Red;
   e.Engine.SetFill(brush);
   e.Engine.SetStroke(brush);
  }
  
  

  

  Please verify the same with the attached sample.
