<p>Thank you for adding CandleStick Chart!<br></p><p>I have 2 questions:</p><p>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?</p><p>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.</p><p>Kamen<br></p><br><br><br><br><br>-------- Оригинално писмо --------<br>От: Werner Pamler <werner.pamler@freenet.de><br>Относно: [Lazarus] TAChart CandleStick Chart<br>До: lazarus@lists.lazarus.freepascal.org<br>Изпратено на: Вторник, 2014, Септември 16 22:09:11 EEST<br><br><br>In r46244 the TOpenHighLowCloseSeries has a new property "Mode": <br>
selection "mOHLC" does the standard painting as before while <br>
"mChandleStick" paints the candlesticks that you requested. Since your <br>
code was mostly a copy of existing code I decided to stick to the old <br>
series type, but just add the painting modes. There are also properties <br>
"CandleStickUpBrush", "CandleStickDownBrush" and "CandleStickLinePen" to <br>
control painting of the up and down bars and the border and shadow line. <br>
I also added a little demo "financial" to the "demo" folder of the <br>
TAChart installation which demonstrates both modes. It would be nice if <br>
you could have a look if everything is fine - I'm not an expert in <br>
financial charts.<br>
<br>
I also fixed the bug which ignored the true minimum of the data - <br>
therefore, it is no longer necessary to calculate the minimum by <br>
yourself, just have a look at the code in the demo project. And, <br>
finally, I modified the AddXOHLC method such that it automatically <br>
initializes the size of the YCount of the chart source if the current <br>
size would not be enough.<br>
