Thank you for adding CandleStick Chart! I have 2 questions: In OHLC tails are in the same color like body but in CandleStick is not. When I change background to black tails hides. How can I make color of the tails like body? Maybe in CandlestickLinePen add option to copy color from body? When I add big portion of data for example 2 years all period are in screen and CandleStick are too small. How can I add HorzScrollBar or something like this and keep the scale of CandleStick? I can zoom it but I want to scroll back to earlier time period. Kamen

Since your code was mostly a copy of existing code I decided to stick to the old series type, but just add the painting modes. There are also properties "CandleStickUpBrush", "CandleStickDownBrush" and "CandleStickLinePen" to control painting of the up and down bars and the border and shadow line. I also added a little demo "financial" to the "demo" folder of the TAChart installation which demonstrates both modes. It would be nice if you could have a look if everything is fine - I'm not an expert in financial charts. I also fixed the bug which ignored the true minimum of the data - therefore, it is no longer necessary to calculate the minimum by yourself, just have a look at the code in the demo project. And, finally, I modified the AddXOHLC method such that it automatically initializes the size of the YCount of the chart source if the current size would not be enough. -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
