开一贴讨论用teechart控件做股票K线图(0分)

在teechart pro 5.2 中如何用自己的库数据来告诉teechart哪个是开盘价，哪个是收盘价等...
以便系统用我们自己的数据来画K线呢?

TeeChart来画股票图不好用,不如自已开发一个,或者找一个控件的;
有这样的例子,坐标系之类,光标停还弹出Hint窗口显示该点的相关信息;
以前我看了一下,不过市面有这样多好用的股票分析系统,所以我没有怎么继续下去;

关注是否有更好的控件,
如果有的话,通知我一声,谢谢,我高分相赠,
意想不到的高分哦.

青侠能不能继续下去，教我们一下如何做？已有程序并不重要，我们主要是在学习。
如果你是想做商业程序，也可以继续下去啊，如果比人家更好，一样可以卖钱。
据说“智超”股票软件可以提供早期源代码画K线的，
我向智超作者的信箱：zhichao2000@email.com.cn
写信无法传递到他的信箱,哪位朋友有他的信箱或是早期的源代码请来一份学习。

请高手续贴讨论

找一个teechar专业版，里面提供了K线图，你只需要把四个价格告诉它即可
我在三年前做股票系统就用的它

找几个CHART控件的源码读一读，你就可以自己做了。

好小伙，居然0分的贴

好家伙，居然看出来是0分的贴... ^o^。我很想给高分，可惜我只有5分了，我很想给5分
但一想：居然只跟5分，太有辱高手了嘛!仅凭这么长的程序给我等初学者，给500分也不够啊
。所以只有给0分。wk_knife不要见怪啊!后来的高手不要没分就不发帖哟!

看完贴后请提前一下，让更多的高手参与进来!
新时代的活雷锋都来参加讨论啊!

teechar专业版，里面提供了K线图，你只需要把四个价格告诉它即可,但如何告诉teechart
，我没学会？指点一下!谢谢!

战晓冬老师的文章我已拜读，我等初学者读来还有点费力，恐怕花费时间较长，
能不能麻烦一下将注释做多点？这个要求可能有点过份。但我想高手在此指定
一下，注释做详细点，我花的时间就少些，进步快一些。我想这是每个初学者
的愿望，望高手成全。谢谢!再谢谢![]

有没有呀....

why_119，有没有什么？你把意思说明白!

用自己的库向teechart提供数据的方法我已解决：
1、要用Data Controls 中的Tdbchart控件。
2、加入一个Table控件。
3、在Tdbchart中的series中的data source中的dataset指定用Table，将Table中active
属性改为true;将dataset中close、open之类的属性和自己库的字段相对应。
4、在Tdchart中的tool栏中加入cursor，并将follow mouse前选中。就可以实现十字线。

还没有解决的问题有如下：
1、如何指定一个屏幕显示指定数目的K线数量，按左箭头和右箭头实现K线图左、右移动。
2、将光标移动某天的K线柱上显示相关的一些注释。

你说的两点我去年都做过了，等下我找找看不家没有。

好，期待你的答案出现

关注中

我放在这儿了，拉吧。
应该全在这里面，都快半年了快忘记了，没重新打开看。
http://cst.mine.nu/stock.rar

wxws兄：
您的程序编译时出现：
error reading series_vol.linepen.endstyleroperty endstyle does not exist.
以下这一点做到了：
将光标移动某天的K线柱上显示相关的一些注释。
但以下一点没做到，应该怎么做？请指教：
1、如何指定一个屏幕显示指定数目的K线数量，按左箭头和右箭头实现K线图左、右移动。
2、按下箭头和上箭头进行K线图的放大和缩小。
3、禁止按住鼠标右键不动移动图形，按住鼠标左键不动后可转动图形。
