Re: A problem with candle series

Hi, The Candle series basically draws a line from High to Low values and a rectangle from Open to Close values. It assumes having a High&Low values both greater or smaller than both Open&Close has no sense. https://en.wikipedia.org/wiki/Candlestick_chart Yes, but what you have mentioned is not the ...

A problem with candle series

Hi,

There is a problem in the attached image. The first data should be charted as a solid T shape, but the resulting vertical line turned out to shift 1 pixel downward that creates a disconnected gap. How can I fix that? thanks. (this one pixel gap gets even worse if I set Border.Visible := False)

I can catch the TChartSeries.OnAfterAdd, OnClearValues events but there i...
